Given numbers are 653, 187, 720, 634

The list of prime factors of all numbers are

Prime factors of 653 are 653

Prime factors of 187 are 11 x 17

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 634 are 2 x 317

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

Given numbers are 653, 187, 720, 634

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

Apply this formula for all numbers.

Step1:

LCM(653, 187) = 122111

GCD(653, 187) = ( 653 x 187 ) / 122111

= 653 / 187

= 653

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 653, 187, 720, 634 is 1
