Therefore, GCD of numbers 858, 366, 80, 171 is 1

Given Input Data is 858, 366, 80, 171

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 366 is 2 x 3 x 61

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 171 is 3 x 3 x 19

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(858, 366) = 52338

GCD(858, 366) = ( 858 x 366 ) / 52338

GCD(858, 366) = 314028 / 52338

GCD(858, 366) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 80

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

LCM(6, 80) = 240

GCD(6, 80) = ( 6 x 80 ) / 240

GCD(6, 80) = 480 / 240

GCD(6, 80) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 171

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

LCM(2, 171) = 342

GCD(2, 171) = ( 2 x 171 ) / 342

GCD(2, 171) = 342 / 342

GCD(2, 171) = 1

GCD of 858, 366, 80, 171 is 1
