Given numbers are 251, 417, 160, 656

The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 417 are 3 x 139

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

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 251, 417, 160, 656

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

Apply this formula for all numbers.

Step1:

LCM(251, 417) = 104667

GCD(251, 417) = ( 251 x 417 ) / 104667

= 251 / 417

= 251

Step2:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

Step3:

LCM(1, 656) = 656

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

= 1 / 656

= 1

So, Greatest Common Divisor of 251, 417, 160, 656 is 1
