Given numbers are 816, 147, 407, 422

The list of prime factors of all numbers are

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 147 are 3 x 7 x 7

Prime factors of 407 are 11 x 37

Prime factors of 422 are 2 x 211

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

Given numbers are 816, 147, 407, 422

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

Apply this formula for all numbers.

Step1:

LCM(816, 147) = 39984

GCD(816, 147) = ( 816 x 147 ) / 39984

= 816 / 147

= 816

Step2:

LCM(3, 407) = 1221

GCD(3, 407) = ( 3 x 407 ) / 1221

= 3 / 407

= 3

Step3:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

So, Greatest Common Divisor of 816, 147, 407, 422 is 1
