Given numbers are 655, 684, 714, 638

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 714 are 2 x 3 x 7 x 17

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 655, 684, 714, 638

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

Apply this formula for all numbers.

Step1:

LCM(655, 684) = 448020

GCD(655, 684) = ( 655 x 684 ) / 448020

= 655 / 684

= 655

Step2:

LCM(1, 714) = 714

GCD(1, 714) = ( 1 x 714 ) / 714

= 1 / 714

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 655, 684, 714, 638 is 1
