Given numbers are 980, 584, 645, 125

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 584 are 2 x 2 x 2 x 73

Prime factors of 645 are 3 x 5 x 43

Prime factors of 125 are 5 x 5 x 5

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

Given numbers are 980, 584, 645, 125

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

Apply this formula for all numbers.

Step1:

LCM(980, 584) = 143080

GCD(980, 584) = ( 980 x 584 ) / 143080

= 980 / 584

= 980

Step2:

LCM(4, 645) = 2580

GCD(4, 645) = ( 4 x 645 ) / 2580

= 4 / 645

= 4

Step3:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

So, Greatest Common Divisor of 980, 584, 645, 125 is 1
