Given numbers are 447, 258, 678, 868

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 258 are 2 x 3 x 43

Prime factors of 678 are 2 x 3 x 113

Prime factors of 868 are 2 x 2 x 7 x 31

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

Given numbers are 447, 258, 678, 868

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

Apply this formula for all numbers.

Step1:

LCM(447, 258) = 38442

GCD(447, 258) = ( 447 x 258 ) / 38442

= 447 / 258

= 447

Step2:

LCM(3, 678) = 678

GCD(3, 678) = ( 3 x 678 ) / 678

= 3 / 678

= 3

Step3:

LCM(3, 868) = 2604

GCD(3, 868) = ( 3 x 868 ) / 2604

= 3 / 868

= 3

So, Greatest Common Divisor of 447, 258, 678, 868 is 1
