Given numbers are 630, 470, 255, 787

The list of prime factors of all numbers are

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

Prime factors of 470 are 2 x 5 x 47

Prime factors of 255 are 3 x 5 x 17

Prime factors of 787 are 787

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

Given numbers are 630, 470, 255, 787

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

Apply this formula for all numbers.

Step1:

LCM(630, 470) = 29610

GCD(630, 470) = ( 630 x 470 ) / 29610

= 630 / 470

= 630

Step2:

LCM(10, 255) = 510

GCD(10, 255) = ( 10 x 255 ) / 510

= 10 / 255

= 10

Step3:

LCM(5, 787) = 3935

GCD(5, 787) = ( 5 x 787 ) / 3935

= 5 / 787

= 5

So, Greatest Common Divisor of 630, 470, 255, 787 is 1
