Given numbers are 128, 460, 630, 475

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 475 are 5 x 5 x 19

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

Given numbers are 128, 460, 630, 475

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

Apply this formula for all numbers.

Step1:

LCM(128, 460) = 14720

GCD(128, 460) = ( 128 x 460 ) / 14720

= 128 / 460

= 128

Step2:

LCM(4, 630) = 1260

GCD(4, 630) = ( 4 x 630 ) / 1260

= 4 / 630

= 4

Step3:

LCM(2, 475) = 950

GCD(2, 475) = ( 2 x 475 ) / 950

= 2 / 475

= 2

So, Greatest Common Divisor of 128, 460, 630, 475 is 1
