Given numbers are 422, 457, 840, 668

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 457 are 457

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 422, 457, 840, 668

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

Apply this formula for all numbers.

Step1:

LCM(422, 457) = 192854

GCD(422, 457) = ( 422 x 457 ) / 192854

= 422 / 457

= 422

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 422, 457, 840, 668 is 1
