Given numbers are 710, 577, 21

The list of prime factors of all numbers are

Prime factors of 710 are 2 x 5 x 71

Prime factors of 577 are 577

Prime factors of 21 are 3 x 7

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

Given numbers are 710, 577, 21

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

Apply this formula for all numbers.

Step1:

LCM(710, 577) = 409670

GCD(710, 577) = ( 710 x 577 ) / 409670

= 710 / 577

= 710

Step2:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

So, Greatest Common Divisor of 710, 577, 21 is 1
