The list of prime factors of all numbers are

Prime factors of 974 are 2 x 487

Prime factors of 557 are 557

Prime factors of 221 are 13 x 17

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 974, 557, 221, 220

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

Apply this formula for all numbers.

Step1:

LCM(974, 557) = 542518

GCD(974, 557) = ( 974 x 557 ) / 542518

= 974 / 557

= 974

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 974, 557, 221, 220 is 1
