Given numbers are 663, 650, 438, 247

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 438 are 2 x 3 x 73

Prime factors of 247 are 13 x 19

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

Given numbers are 663, 650, 438, 247

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

Apply this formula for all numbers.

Step1:

LCM(663, 650) = 33150

GCD(663, 650) = ( 663 x 650 ) / 33150

= 663 / 650

= 663

Step2:

LCM(13, 438) = 5694

GCD(13, 438) = ( 13 x 438 ) / 5694

= 13 / 438

= 13

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 663, 650, 438, 247 is 1
