Given numbers are 707, 620, 721, 872

The list of prime factors of all numbers are

Prime factors of 707 are 7 x 101

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 721 are 7 x 103

Prime factors of 872 are 2 x 2 x 2 x 109

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

Given numbers are 707, 620, 721, 872

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

Apply this formula for all numbers.

Step1:

LCM(707, 620) = 438340

GCD(707, 620) = ( 707 x 620 ) / 438340

= 707 / 620

= 707

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 707, 620, 721, 872 is 1
