Given numbers are 408, 812, 775, 166

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 775 are 5 x 5 x 31

Prime factors of 166 are 2 x 83

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

Given numbers are 408, 812, 775, 166

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

Apply this formula for all numbers.

Step1:

LCM(408, 812) = 82824

GCD(408, 812) = ( 408 x 812 ) / 82824

= 408 / 812

= 408

Step2:

LCM(4, 775) = 3100

GCD(4, 775) = ( 4 x 775 ) / 3100

= 4 / 775

= 4

Step3:

LCM(1, 166) = 166

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

= 1 / 166

= 1

So, Greatest Common Divisor of 408, 812, 775, 166 is 1
