Given numbers are 660, 574, 744, 285

The list of prime factors of all numbers are

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

Prime factors of 574 are 2 x 7 x 41

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

Prime factors of 285 are 3 x 5 x 19

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

Given numbers are 660, 574, 744, 285

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

Apply this formula for all numbers.

Step1:

LCM(660, 574) = 189420

GCD(660, 574) = ( 660 x 574 ) / 189420

= 660 / 574

= 660

Step2:

LCM(2, 744) = 744

GCD(2, 744) = ( 2 x 744 ) / 744

= 2 / 744

= 2

Step3:

LCM(2, 285) = 570

GCD(2, 285) = ( 2 x 285 ) / 570

= 2 / 285

= 2

So, Greatest Common Divisor of 660, 574, 744, 285 is 1
