This allows us to identify common factors and combine factors efficiently.<\/p>\n\n\n\n<p>Starting with 714, we divide by the smallest prime number 2, since it is even. Continuing with 3, 7, and 17, we end up with 2 \u00d7 3 \u00d7 7 \u00d7 17. These are the prime numbers whose product is 714. For 135, we divide by 3 until it is no longer divisible, and then use 5. This gives 3\u00b3 \u00d7 5.<\/p>\n\n\n\n<p>For the HCF, we look at what prime factors appear in both factorizations. The only common factor is 3, and since 714 has just one 3, we take the lowest power. So, the HCF is 3. This tells us that 3 is the largest number that can divide both 714 and 135 without leaving a remainder.<\/p>\n\n\n\n<p>To find the LCM, we take all prime factors involved in both numbers, but we take the highest power of each. That includes 2\u00b9, 3\u00b3, 5\u00b9, 7\u00b9, and 17\u00b9. Multiplying these gives the smallest number that is a multiple of both original numbers.<\/p>\n\n\n\n<p>Using the prime factorization method ensures accuracy and gives a clear view of the relationship between the two numbers. It is particularly useful in mathematics, engineering, and computer science, where factorization plays a key role in algorithms and problem solving.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-52.jpeg\" alt=\"\" class=\"wp-image-25547\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-52.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-52-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-52-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Find the hcf and lcm of 714 and 135 by prime factorization method The Correct Answer and Explanation is: To find the HCF (Highest Common Factor) and LCM (Least Common Multiple) of 714 and 135 using the prime factorization method, follow these steps: Step 1: Prime Factorization 714:714 is even, so divide by 2714 \u00f7 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-25546","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/25546","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=25546"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/25546\/revisions"}],"predecessor-version":[{"id":25548,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/25546\/revisions\/25548"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=25546"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=25546"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=25546"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
