Given numbers are 980, 221, 757, 656

The list of prime factors of all numbers are

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 221 are 13 x 17

Prime factors of 757 are 757

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 980, 221, 757, 656

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

Apply this formula for all numbers.

Step1:

LCM(980, 221) = 216580

GCD(980, 221) = ( 980 x 221 ) / 216580

= 980 / 221

= 980

Step2:

LCM(1, 757) = 757

GCD(1, 757) = ( 1 x 757 ) / 757

= 1 / 757

= 1

Step3:

LCM(1, 656) = 656

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

= 1 / 656

= 1

So, Greatest Common Divisor of 980, 221, 757, 656 is 1
