Given numbers are 627, 780, 980, 394

The list of prime factors of all numbers are

Prime factors of 627 are 3 x 11 x 19

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

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 394 are 2 x 197

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

Given numbers are 627, 780, 980, 394

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

Apply this formula for all numbers.

Step1:

LCM(627, 780) = 163020

GCD(627, 780) = ( 627 x 780 ) / 163020

= 627 / 780

= 627

Step2:

LCM(3, 980) = 2940

GCD(3, 980) = ( 3 x 980 ) / 2940

= 3 / 980

= 3

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 627, 780, 980, 394 is 1
