Given numbers are 868, 381, 406, 858

The list of prime factors of all numbers are

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

Prime factors of 381 are 3 x 127

Prime factors of 406 are 2 x 7 x 29

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 868, 381, 406, 858

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

Apply this formula for all numbers.

Step1:

LCM(868, 381) = 330708

GCD(868, 381) = ( 868 x 381 ) / 330708

= 868 / 381

= 868

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 858) = 858

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

= 1 / 858

= 1

So, Greatest Common Divisor of 868, 381, 406, 858 is 1
