The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 579 are 3 x 193

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

Prime factors of 418 are 2 x 11 x 19

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

Given numbers are 648, 579, 980, 418

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

Apply this formula for all numbers.

Step1:

LCM(648, 579) = 125064

GCD(648, 579) = ( 648 x 579 ) / 125064

= 648 / 579

= 648

Step2:

LCM(3, 980) = 2940

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

= 3 / 980

= 3

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 648, 579, 980, 418 is 1
