Given numbers are 668, 177, 447, 858

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

Prime factors of 177 are 3 x 59

Prime factors of 447 are 3 x 149

Prime factors of 858 are 2 x 3 x 11 x 13

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

Given numbers are 668, 177, 447, 858

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

Apply this formula for all numbers.

Step1:

LCM(668, 177) = 118236

GCD(668, 177) = ( 668 x 177 ) / 118236

= 668 / 177

= 668

Step2:

LCM(1, 447) = 447

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

= 1 / 447

= 1

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 668, 177, 447, 858 is 1
