Given numbers are 308, 630, 430, 617

The list of prime factors of all numbers are

Prime factors of 308 are 2 x 2 x 7 x 11

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

Prime factors of 430 are 2 x 5 x 43

Prime factors of 617 are 617

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

Given numbers are 308, 630, 430, 617

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

Apply this formula for all numbers.

Step1:

LCM(308, 630) = 13860

GCD(308, 630) = ( 308 x 630 ) / 13860

= 308 / 630

= 308

Step2:

LCM(14, 430) = 3010

GCD(14, 430) = ( 14 x 430 ) / 3010

= 14 / 430

= 14

Step3:

LCM(2, 617) = 1234

GCD(2, 617) = ( 2 x 617 ) / 1234

= 2 / 617

= 2

So, Greatest Common Divisor of 308, 630, 430, 617 is 1
