Given numbers are 980, 847, 948, 688

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 847 are 7 x 11 x 11

Prime factors of 948 are 2 x 2 x 3 x 79

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

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

Given numbers are 980, 847, 948, 688

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

Apply this formula for all numbers.

Step1:

LCM(980, 847) = 118580

GCD(980, 847) = ( 980 x 847 ) / 118580

= 980 / 847

= 980

Step2:

LCM(7, 948) = 6636

GCD(7, 948) = ( 7 x 948 ) / 6636

= 7 / 948

= 7

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 980, 847, 948, 688 is 1
