Given numbers are 640, 340, 450, 401

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 401 are 401

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

Given numbers are 640, 340, 450, 401

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

Apply this formula for all numbers.

Step1:

LCM(640, 340) = 10880

GCD(640, 340) = ( 640 x 340 ) / 10880

= 640 / 340

= 640

Step2:

LCM(20, 450) = 900

GCD(20, 450) = ( 20 x 450 ) / 900

= 20 / 450

= 20

Step3:

LCM(10, 401) = 4010

GCD(10, 401) = ( 10 x 401 ) / 4010

= 10 / 401

= 10

So, Greatest Common Divisor of 640, 340, 450, 401 is 1
