Given numbers are 222, 170, 921, 447

The list of prime factors of all numbers are

Prime factors of 222 are 2 x 3 x 37

Prime factors of 170 are 2 x 5 x 17

Prime factors of 921 are 3 x 307

Prime factors of 447 are 3 x 149

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

Given numbers are 222, 170, 921, 447

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

Apply this formula for all numbers.

Step1:

LCM(222, 170) = 18870

GCD(222, 170) = ( 222 x 170 ) / 18870

= 222 / 170

= 222

Step2:

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

= 2 / 921

= 2

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 222, 170, 921, 447 is 1
