Given numbers are 980, 925, 623, 647

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 925 are 5 x 5 x 37

Prime factors of 623 are 7 x 89

Prime factors of 647 are 647

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

Given numbers are 980, 925, 623, 647

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

Apply this formula for all numbers.

Step1:

LCM(980, 925) = 181300

GCD(980, 925) = ( 980 x 925 ) / 181300

= 980 / 925

= 980

Step2:

LCM(5, 623) = 3115

GCD(5, 623) = ( 5 x 623 ) / 3115

= 5 / 623

= 5

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 980, 925, 623, 647 is 1
