Given numbers are 818, 166, 145, 406

The list of prime factors of all numbers are

Prime factors of 818 are 2 x 409

Prime factors of 166 are 2 x 83

Prime factors of 145 are 5 x 29

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 818, 166, 145, 406

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

Apply this formula for all numbers.

Step1:

LCM(818, 166) = 67894

GCD(818, 166) = ( 818 x 166 ) / 67894

= 818 / 166

= 818

Step2:

LCM(2, 145) = 290

GCD(2, 145) = ( 2 x 145 ) / 290

= 2 / 145

= 2

Step3:

LCM(1, 406) = 406

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

= 1 / 406

= 1

So, Greatest Common Divisor of 818, 166, 145, 406 is 1
