Given numbers are 438, 828, 647, 170

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 647 are 647

Prime factors of 170 are 2 x 5 x 17

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

Given numbers are 438, 828, 647, 170

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

Apply this formula for all numbers.

Step1:

LCM(438, 828) = 60444

GCD(438, 828) = ( 438 x 828 ) / 60444

= 438 / 828

= 438

Step2:

LCM(6, 647) = 3882

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

= 6 / 647

= 6

Step3:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

So, Greatest Common Divisor of 438, 828, 647, 170 is 1
