Given numbers are 665, 500, 156, 656

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

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

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Given numbers are 665, 500, 156, 656

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

Apply this formula for all numbers.

Step1:

LCM(665, 500) = 66500

GCD(665, 500) = ( 665 x 500 ) / 66500

= 665 / 500

= 665

Step2:

LCM(5, 156) = 780

GCD(5, 156) = ( 5 x 156 ) / 780

= 5 / 156

= 5

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 665, 500, 156, 656 is 1
