Given numbers are 422, 626, 809, 840

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 626 are 2 x 313

Prime factors of 809 are 809

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

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

Given numbers are 422, 626, 809, 840

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

Apply this formula for all numbers.

Step1:

LCM(422, 626) = 132086

GCD(422, 626) = ( 422 x 626 ) / 132086

= 422 / 626

= 422

Step2:

LCM(2, 809) = 1618

GCD(2, 809) = ( 2 x 809 ) / 1618

= 2 / 809

= 2

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 422, 626, 809, 840 is 1
