Given numbers are 442, 457, 773, 720

The list of prime factors of all numbers are

Prime factors of 442 are 2 x 13 x 17

Prime factors of 457 are 457

Prime factors of 773 are 773

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 442, 457, 773, 720

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

Apply this formula for all numbers.

Step1:

LCM(442, 457) = 201994

GCD(442, 457) = ( 442 x 457 ) / 201994

= 442 / 457

= 442

Step2:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 442, 457, 773, 720 is 1
