Given numbers are 721, 220, 806, 710

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 806 are 2 x 13 x 31

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 721, 220, 806, 710

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

Apply this formula for all numbers.

Step1:

LCM(721, 220) = 158620

GCD(721, 220) = ( 721 x 220 ) / 158620

= 721 / 220

= 721

Step2:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

Step3:

LCM(1, 710) = 710

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

= 1 / 710

= 1

So, Greatest Common Divisor of 721, 220, 806, 710 is 1
