Given numbers are 860, 422, 222, 643

The list of prime factors of all numbers are

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 422 are 2 x 211

Prime factors of 222 are 2 x 3 x 37

Prime factors of 643 are 643

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

Given numbers are 860, 422, 222, 643

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

Apply this formula for all numbers.

Step1:

LCM(860, 422) = 181460

GCD(860, 422) = ( 860 x 422 ) / 181460

= 860 / 422

= 860

Step2:

LCM(2, 222) = 222

GCD(2, 222) = ( 2 x 222 ) / 222

= 2 / 222

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 860, 422, 222, 643 is 1
