Given numbers are 721, 738, 66, 676

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 66 are 2 x 3 x 11

Prime factors of 676 are 2 x 2 x 13 x 13

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

Given numbers are 721, 738, 66, 676

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

Apply this formula for all numbers.

Step1:

LCM(721, 738) = 532098

GCD(721, 738) = ( 721 x 738 ) / 532098

= 721 / 738

= 721

Step2:

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

= 1 / 66

= 1

Step3:

LCM(1, 676) = 676

GCD(1, 676) = ( 1 x 676 ) / 676

= 1 / 676

= 1

So, Greatest Common Divisor of 721, 738, 66, 676 is 1
