Given numbers are 708, 634, 387, 220

The list of prime factors of all numbers are

Prime factors of 708 are 2 x 2 x 3 x 59

Prime factors of 634 are 2 x 317

Prime factors of 387 are 3 x 3 x 43

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

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

Given numbers are 708, 634, 387, 220

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

Apply this formula for all numbers.

Step1:

LCM(708, 634) = 224436

GCD(708, 634) = ( 708 x 634 ) / 224436

= 708 / 634

= 708

Step2:

LCM(2, 387) = 774

GCD(2, 387) = ( 2 x 387 ) / 774

= 2 / 387

= 2

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 708, 634, 387, 220 is 1
