Given numbers are 680, 627, 780, 653

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 627 are 3 x 11 x 19

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 653 are 653

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

Given numbers are 680, 627, 780, 653

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

Apply this formula for all numbers.

Step1:

LCM(680, 627) = 426360

GCD(680, 627) = ( 680 x 627 ) / 426360

= 680 / 627

= 680

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 680, 627, 780, 653 is 1
