Given numbers are 986, 640, 422, 143

The list of prime factors of all numbers are

Prime factors of 986 are 2 x 17 x 29

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

Prime factors of 422 are 2 x 211

Prime factors of 143 are 11 x 13

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

Given numbers are 986, 640, 422, 143

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

Apply this formula for all numbers.

Step1:

LCM(986, 640) = 315520

GCD(986, 640) = ( 986 x 640 ) / 315520

= 986 / 640

= 986

Step2:

LCM(2, 422) = 422

GCD(2, 422) = ( 2 x 422 ) / 422

= 2 / 422

= 2

Step3:

LCM(2, 143) = 286

GCD(2, 143) = ( 2 x 143 ) / 286

= 2 / 143

= 2

So, Greatest Common Divisor of 986, 640, 422, 143 is 1
