Given numbers are 646, 460, 401

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 401 are 401

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

Given numbers are 646, 460, 401

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

Apply this formula for all numbers.

Step1:

LCM(646, 460) = 148580

GCD(646, 460) = ( 646 x 460 ) / 148580

= 646 / 460

= 646

Step2:

LCM(2, 401) = 802

GCD(2, 401) = ( 2 x 401 ) / 802

= 2 / 401

= 2

So, Greatest Common Divisor of 646, 460, 401 is 1
