The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 721 are 7 x 103

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 974 are 2 x 487

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

Given numbers are 215, 721, 676, 974

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

Apply this formula for all numbers.

Step1:

LCM(215, 721) = 155015

GCD(215, 721) = ( 215 x 721 ) / 155015

= 215 / 721

= 215

Step2:

LCM(1, 676) = 676

GCD(1, 676) = ( 1 x 676 ) / 676

= 1 / 676

= 1

Step3:

LCM(1, 974) = 974

GCD(1, 974) = ( 1 x 974 ) / 974

= 1 / 974

= 1

So, Greatest Common Divisor of 215, 721, 676, 974 is 1
