Given numbers are 721, 786, 576, 427

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 786 are 2 x 3 x 131

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 427 are 7 x 61

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

Given numbers are 721, 786, 576, 427

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

Apply this formula for all numbers.

Step1:

LCM(721, 786) = 566706

GCD(721, 786) = ( 721 x 786 ) / 566706

= 721 / 786

= 721

Step2:

LCM(1, 576) = 576

GCD(1, 576) = ( 1 x 576 ) / 576

= 1 / 576

= 1

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 721, 786, 576, 427 is 1
