WebHCF By Prime Factorization Method Follow the below-given steps to find the HCF of numbers using the prime factorisation method. Step 1: Write each number as a product of its prime factors. This method is called here prime factorization. Step 2: Now list the common factors of both the numbers WebThe first step to find the gcf of 84 and 231 is to list the factors of each number. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84. The factors of 231 are 1, 3, 7, 11, 21, 33, 77 and 231. So, the Greatest Common Factor for these numbers is 21 because it divides all them without a remainder. Read more about Common Factors below.
HCF of 36 and 42 How to Find HCF of 36, 42? - Cuemath
WebHCF of 455 and 42 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. Step 1: Divide 455 (larger number) by 42 (smaller number). Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (42) by the remainder (35). Step 3: Repeat this process until the remainder = 0. WebStep 1: Break down into prime factors. 16 = 2 x 2 x 3 = 22 x 3. 32 = 2 x 2 x 2 x 2 = 24. Step 2: Identify similar factors. Both numbers have 22 as their factors. Step 3: Multiply the common factors. 22 = 2 x 2 = 4. Hence 4 is the HCF of 16 and 32 . To learn more about LCM and HCF, head over to the LCM calculator and GCF calculator. ff14 rptools plugin
