Given numbers are 401, 207, 348, 640

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 207 are 3 x 3 x 23

Prime factors of 348 are 2 x 2 x 3 x 29

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

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

Given numbers are 401, 207, 348, 640

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

Apply this formula for all numbers.

Step1:

LCM(401, 207) = 83007

GCD(401, 207) = ( 401 x 207 ) / 83007

= 401 / 207

= 401

Step2:

LCM(1, 348) = 348

GCD(1, 348) = ( 1 x 348 ) / 348

= 1 / 348

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 401, 207, 348, 640 is 1
