Given numbers are 637, 665, 980, 618

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 665 are 5 x 7 x 19

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

Prime factors of 618 are 2 x 3 x 103

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

Given numbers are 637, 665, 980, 618

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

Apply this formula for all numbers.

Step1:

LCM(637, 665) = 60515

GCD(637, 665) = ( 637 x 665 ) / 60515

= 637 / 665

= 637

Step2:

LCM(7, 980) = 980

GCD(7, 980) = ( 7 x 980 ) / 980

= 7 / 980

= 7

Step3:

LCM(7, 618) = 4326

GCD(7, 618) = ( 7 x 618 ) / 4326

= 7 / 618

= 7

So, Greatest Common Divisor of 637, 665, 980, 618 is 1
