Given numbers are 405, 400, 679, 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 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 679 are 7 x 97

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, 400, 679, 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, 400) = 32400

GCD(405, 400) = ( 405 x 400 ) / 32400

= 405 / 400

= 405

Step2:

LCM(5, 679) = 3395

GCD(5, 679) = ( 5 x 679 ) / 3395

= 5 / 679

= 5

Step3:

LCM(1, 418) = 418

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

= 1 / 418

= 1

So, Greatest Common Divisor of 405, 400, 679, 418 is 1
