Given numbers are 680, 426, 635, 981

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 426 are 2 x 3 x 71

Prime factors of 635 are 5 x 127

Prime factors of 981 are 3 x 3 x 109

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

Given numbers are 680, 426, 635, 981

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

Apply this formula for all numbers.

Step1:

LCM(680, 426) = 144840

GCD(680, 426) = ( 680 x 426 ) / 144840

= 680 / 426

= 680

Step2:

LCM(2, 635) = 1270

GCD(2, 635) = ( 2 x 635 ) / 1270

= 2 / 635

= 2

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 680, 426, 635, 981 is 1
