Given numbers are 858, 867, 666, 397

The list of prime factors of all numbers are

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

Prime factors of 867 are 3 x 17 x 17

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 397 are 397

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

Given numbers are 858, 867, 666, 397

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

Apply this formula for all numbers.

Step1:

LCM(858, 867) = 247962

GCD(858, 867) = ( 858 x 867 ) / 247962

= 858 / 867

= 858

Step2:

LCM(3, 666) = 666

GCD(3, 666) = ( 3 x 666 ) / 666

= 3 / 666

= 3

Step3:

LCM(3, 397) = 1191

GCD(3, 397) = ( 3 x 397 ) / 1191

= 3 / 397

= 3

So, Greatest Common Divisor of 858, 867, 666, 397 is 1
