Given numbers are 744, 252, 663, 398

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 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 663 are 3 x 13 x 17

Prime factors of 398 are 2 x 199

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

Given numbers are 744, 252, 663, 398

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

Apply this formula for all numbers.

Step1:

LCM(744, 252) = 15624

GCD(744, 252) = ( 744 x 252 ) / 15624

= 744 / 252

= 744

Step2:

LCM(12, 663) = 2652

GCD(12, 663) = ( 12 x 663 ) / 2652

= 12 / 663

= 12

Step3:

LCM(3, 398) = 1194

GCD(3, 398) = ( 3 x 398 ) / 1194

= 3 / 398

= 3

So, Greatest Common Divisor of 744, 252, 663, 398 is 1
