Given numbers are 406, 855, 166, 428

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 166 are 2 x 83

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 406, 855, 166, 428

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

Apply this formula for all numbers.

Step1:

LCM(406, 855) = 347130

GCD(406, 855) = ( 406 x 855 ) / 347130

= 406 / 855

= 406

Step2:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 406, 855, 166, 428 is 1
