Given numbers are 520, 656, 651, 238

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Prime factors of 651 are 3 x 7 x 31

Prime factors of 238 are 2 x 7 x 17

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

Given numbers are 520, 656, 651, 238

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

Apply this formula for all numbers.

Step1:

LCM(520, 656) = 42640

GCD(520, 656) = ( 520 x 656 ) / 42640

= 520 / 656

= 520

Step2:

LCM(8, 651) = 5208

GCD(8, 651) = ( 8 x 651 ) / 5208

= 8 / 651

= 8

Step3:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

So, Greatest Common Divisor of 520, 656, 651, 238 is 1
