Given numbers are 656, 574, 130, 161

The list of prime factors of all numbers are

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

Prime factors of 574 are 2 x 7 x 41

Prime factors of 130 are 2 x 5 x 13

Prime factors of 161 are 7 x 23

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

Given numbers are 656, 574, 130, 161

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

Apply this formula for all numbers.

Step1:

LCM(656, 574) = 4592

GCD(656, 574) = ( 656 x 574 ) / 4592

= 656 / 574

= 656

Step2:

LCM(82, 130) = 5330

GCD(82, 130) = ( 82 x 130 ) / 5330

= 82 / 130

= 82

Step3:

LCM(2, 161) = 322

GCD(2, 161) = ( 2 x 161 ) / 322

= 2 / 161

= 2

So, Greatest Common Divisor of 656, 574, 130, 161 is 1
