Given numbers are 120, 441, 728, 681

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 681 are 3 x 227

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

Given numbers are 120, 441, 728, 681

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

Apply this formula for all numbers.

Step1:

LCM(120, 441) = 17640

GCD(120, 441) = ( 120 x 441 ) / 17640

= 120 / 441

= 120

Step2:

LCM(3, 728) = 2184

GCD(3, 728) = ( 3 x 728 ) / 2184

= 3 / 728

= 3

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 120, 441, 728, 681 is 1
