Given numbers are 406, 616, 621, 456

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 406, 616, 621, 456

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

Apply this formula for all numbers.

Step1:

LCM(406, 616) = 17864

GCD(406, 616) = ( 406 x 616 ) / 17864

= 406 / 616

= 406

Step2:

LCM(14, 621) = 8694

GCD(14, 621) = ( 14 x 621 ) / 8694

= 14 / 621

= 14

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 406, 616, 621, 456 is 1
