Given numbers are 310, 645, 434, 418

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 645 are 3 x 5 x 43

Prime factors of 434 are 2 x 7 x 31

Prime factors of 418 are 2 x 11 x 19

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

Given numbers are 310, 645, 434, 418

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

Apply this formula for all numbers.

Step1:

LCM(310, 645) = 39990

GCD(310, 645) = ( 310 x 645 ) / 39990

= 310 / 645

= 310

Step2:

LCM(5, 434) = 2170

GCD(5, 434) = ( 5 x 434 ) / 2170

= 5 / 434

= 5

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 310, 645, 434, 418 is 1
