The list of prime factors of all numbers are

Prime factors of 947 are 947

Prime factors of 988 are 2 x 2 x 13 x 19

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

Prime factors of 458 are 2 x 229

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

Given numbers are 947, 988, 780, 458

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

Apply this formula for all numbers.

Step1:

LCM(947, 988) = 935636

GCD(947, 988) = ( 947 x 988 ) / 935636

= 947 / 988

= 947

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 947, 988, 780, 458 is 1
