Given numbers are 721, 764, 386, 456

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 764 are 2 x 2 x 191

Prime factors of 386 are 2 x 193

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 721, 764, 386, 456

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

Apply this formula for all numbers.

Step1:

LCM(721, 764) = 550844

GCD(721, 764) = ( 721 x 764 ) / 550844

= 721 / 764

= 721

Step2:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 721, 764, 386, 456 is 1
