Given numbers are 161, 620, 422

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 620 are 2 x 2 x 5 x 31

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 161, 620, 422

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

Apply this formula for all numbers.

Step1:

LCM(161, 620) = 99820

GCD(161, 620) = ( 161 x 620 ) / 99820

= 161 / 620

= 161

Step2:

LCM(1, 422) = 422

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

= 1 / 422

= 1

So, Greatest Common Divisor of 161, 620, 422 is 1
