Question

Find the HCF of the following numbers by prime factorization method first 7628 second 24 16363 3864 82

Answer 1

Step-by-step explanation:

1) 76, 28

76=2 x 2 x 19

28=2 x 2 x 7

HCF(28,76)=2 x 2

HCF(28,76)=4

2) 24,16,36

16=2 x 2 x 2 x 2

24=2 x 2 x 2 x 3

36=2 x 2 x 3 x 3

HCF(16,24,36)=2 x 2

HCF(16,24,36)=4

3) 38, 64, 82

38=2 x 19

64=2 x 2 x 2 x 2 x 2 x 2

82=2 x 41

HCF(38, 64, 82)=2

HCF(38, 64, 82)=2
