Given numbers are 744, 660, 422, 287

The list of prime factors of all numbers are

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 422 are 2 x 211

Prime factors of 287 are 7 x 41

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

Given numbers are 744, 660, 422, 287

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

Apply this formula for all numbers.

Step1:

LCM(744, 660) = 40920

GCD(744, 660) = ( 744 x 660 ) / 40920

= 744 / 660

= 744

Step2:

LCM(12, 422) = 2532

GCD(12, 422) = ( 12 x 422 ) / 2532

= 12 / 422

= 12

Step3:

LCM(2, 287) = 574

GCD(2, 287) = ( 2 x 287 ) / 574

= 2 / 287

= 2

So, Greatest Common Divisor of 744, 660, 422, 287 is 1
