Given numbers are 405, 630, 372, 418

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Prime factors of 372 are 2 x 2 x 3 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 405, 630, 372, 418

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

Apply this formula for all numbers.

Step1:

LCM(405, 630) = 5670

GCD(405, 630) = ( 405 x 630 ) / 5670

= 405 / 630

= 405

Step2:

LCM(45, 372) = 5580

GCD(45, 372) = ( 45 x 372 ) / 5580

= 45 / 372

= 45

Step3:

LCM(3, 418) = 1254

GCD(3, 418) = ( 3 x 418 ) / 1254

= 3 / 418

= 3

So, Greatest Common Divisor of 405, 630, 372, 418 is 1
