Given numbers are 688, 780, 351, 974

The list of prime factors of all numbers are

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 351 are 3 x 3 x 3 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 688, 780, 351, 974

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

Apply this formula for all numbers.

Step1:

LCM(688, 780) = 134160

GCD(688, 780) = ( 688 x 780 ) / 134160

= 688 / 780

= 688

Step2:

LCM(4, 351) = 1404

GCD(4, 351) = ( 4 x 351 ) / 1404

= 4 / 351

= 4

Step3:

LCM(1, 974) = 974

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

= 1 / 974

= 1

So, Greatest Common Divisor of 688, 780, 351, 974 is 1
