Given numbers are 470, 624, 395, 165

The list of prime factors of all numbers are

Prime factors of 470 are 2 x 5 x 47

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 395 are 5 x 79

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 470, 624, 395, 165

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

Apply this formula for all numbers.

Step1:

LCM(470, 624) = 146640

GCD(470, 624) = ( 470 x 624 ) / 146640

= 470 / 624

= 470

Step2:

LCM(2, 395) = 790

GCD(2, 395) = ( 2 x 395 ) / 790

= 2 / 395

= 2

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 470, 624, 395, 165 is 1
