Given numbers are 170, 912, 420, 947

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 947 are 947

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

Given numbers are 170, 912, 420, 947

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

Apply this formula for all numbers.

Step1:

LCM(170, 912) = 77520

GCD(170, 912) = ( 170 x 912 ) / 77520

= 170 / 912

= 170

Step2:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

Step3:

LCM(2, 947) = 1894

GCD(2, 947) = ( 2 x 947 ) / 1894

= 2 / 947

= 2

So, Greatest Common Divisor of 170, 912, 420, 947 is 1
