Given numbers are 156, 637, 748, 658

The list of prime factors of all numbers are

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 637 are 7 x 7 x 13

Prime factors of 748 are 2 x 2 x 11 x 17

Prime factors of 658 are 2 x 7 x 47

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 156, 637, 748, 658

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(156, 637) = 7644

GCD(156, 637) = ( 156 x 637 ) / 7644

= 156 / 637

= 156

Step2:

LCM(13, 748) = 9724

GCD(13, 748) = ( 13 x 748 ) / 9724

= 13 / 748

= 13

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 156, 637, 748, 658 is 1
