Given numbers are 166, 381, 990, 427

The list of prime factors of all numbers are

Prime factors of 166 are 2 x 83

Prime factors of 381 are 3 x 127

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 427 are 7 x 61

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

Given numbers are 166, 381, 990, 427

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

Apply this formula for all numbers.

Step1:

LCM(166, 381) = 63246

GCD(166, 381) = ( 166 x 381 ) / 63246

= 166 / 381

= 166

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 166, 381, 990, 427 is 1
