Given numbers are 438, 246, 570, 647

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 246 are 2 x 3 x 41

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 647 are 647

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

Given numbers are 438, 246, 570, 647

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

Apply this formula for all numbers.

Step1:

LCM(438, 246) = 17958

GCD(438, 246) = ( 438 x 246 ) / 17958

= 438 / 246

= 438

Step2:

LCM(6, 570) = 570

GCD(6, 570) = ( 6 x 570 ) / 570

= 6 / 570

= 6

Step3:

LCM(6, 647) = 3882

GCD(6, 647) = ( 6 x 647 ) / 3882

= 6 / 647

= 6

So, Greatest Common Divisor of 438, 246, 570, 647 is 1
