Given numbers are 921, 654, 680, 710

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 654 are 2 x 3 x 109

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

Prime factors of 710 are 2 x 5 x 71

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

Given numbers are 921, 654, 680, 710

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

Apply this formula for all numbers.

Step1:

LCM(921, 654) = 200778

GCD(921, 654) = ( 921 x 654 ) / 200778

= 921 / 654

= 921

Step2:

LCM(3, 680) = 2040

GCD(3, 680) = ( 3 x 680 ) / 2040

= 3 / 680

= 3

Step3:

LCM(1, 710) = 710

GCD(1, 710) = ( 1 x 710 ) / 710

= 1 / 710

= 1

So, Greatest Common Divisor of 921, 654, 680, 710 is 1
