Given numbers are 680, 921, 780, 910

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 921 are 3 x 307

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

Prime factors of 910 are 2 x 5 x 7 x 13

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

Given numbers are 680, 921, 780, 910

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

Apply this formula for all numbers.

Step1:

LCM(680, 921) = 626280

GCD(680, 921) = ( 680 x 921 ) / 626280

= 680 / 921

= 680

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

= 1 / 910

= 1

So, Greatest Common Divisor of 680, 921, 780, 910 is 1
