Given numbers are 420, 664, 773, 240

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 773 are 773

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 420, 664, 773, 240

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

Apply this formula for all numbers.

Step1:

LCM(420, 664) = 69720

GCD(420, 664) = ( 420 x 664 ) / 69720

= 420 / 664

= 420

Step2:

LCM(4, 773) = 3092

GCD(4, 773) = ( 4 x 773 ) / 3092

= 4 / 773

= 4

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 420, 664, 773, 240 is 1
