Given numbers are 470, 638, 361, 135

The list of prime factors of all numbers are

Prime factors of 470 are 2 x 5 x 47

Prime factors of 638 are 2 x 11 x 29

Prime factors of 361 are 19 x 19

Prime factors of 135 are 3 x 3 x 3 x 5

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

Given numbers are 470, 638, 361, 135

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

Apply this formula for all numbers.

Step1:

LCM(470, 638) = 149930

GCD(470, 638) = ( 470 x 638 ) / 149930

= 470 / 638

= 470

Step2:

LCM(2, 361) = 722

GCD(2, 361) = ( 2 x 361 ) / 722

= 2 / 361

= 2

Step3:

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

= 1 / 135

= 1

So, Greatest Common Divisor of 470, 638, 361, 135 is 1
