Given numbers are 220, 108, 639, 246

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

Prime factors of 639 are 3 x 3 x 71

Prime factors of 246 are 2 x 3 x 41

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

Given numbers are 220, 108, 639, 246

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

Apply this formula for all numbers.

Step1:

LCM(220, 108) = 5940

GCD(220, 108) = ( 220 x 108 ) / 5940

= 220 / 108

= 220

Step2:

LCM(4, 639) = 2556

GCD(4, 639) = ( 4 x 639 ) / 2556

= 4 / 639

= 4

Step3:

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

= 1 / 246

= 1

So, Greatest Common Divisor of 220, 108, 639, 246 is 1
