Given numbers are 218, 493, 631, 660

The list of prime factors of all numbers are

Prime factors of 218 are 2 x 109

Prime factors of 493 are 17 x 29

Prime factors of 631 are 631

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 218, 493, 631, 660

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

Apply this formula for all numbers.

Step1:

LCM(218, 493) = 107474

GCD(218, 493) = ( 218 x 493 ) / 107474

= 218 / 493

= 218

Step2:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 218, 493, 631, 660 is 1
