Given numbers are 408, 850, 665, 422

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 850 are 2 x 5 x 5 x 17

Prime factors of 665 are 5 x 7 x 19

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 408, 850, 665, 422

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

Apply this formula for all numbers.

Step1:

LCM(408, 850) = 10200

GCD(408, 850) = ( 408 x 850 ) / 10200

= 408 / 850

= 408

Step2:

LCM(34, 665) = 22610

GCD(34, 665) = ( 34 x 665 ) / 22610

= 34 / 665

= 34

Step3:

LCM(1, 422) = 422

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

= 1 / 422

= 1

So, Greatest Common Divisor of 408, 850, 665, 422 is 1
