Given numbers are 721, 623, 710, 822

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 623 are 7 x 89

Prime factors of 710 are 2 x 5 x 71

Prime factors of 822 are 2 x 3 x 137

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

Given numbers are 721, 623, 710, 822

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

Apply this formula for all numbers.

Step1:

LCM(721, 623) = 64169

GCD(721, 623) = ( 721 x 623 ) / 64169

= 721 / 623

= 721

Step2:

LCM(7, 710) = 4970

GCD(7, 710) = ( 7 x 710 ) / 4970

= 7 / 710

= 7

Step3:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

So, Greatest Common Divisor of 721, 623, 710, 822 is 1
