Given numbers are 889, 408, 222, 646

The list of prime factors of all numbers are

Prime factors of 889 are 7 x 127

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 222 are 2 x 3 x 37

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 889, 408, 222, 646

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

Apply this formula for all numbers.

Step1:

LCM(889, 408) = 362712

GCD(889, 408) = ( 889 x 408 ) / 362712

= 889 / 408

= 889

Step2:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 889, 408, 222, 646 is 1
