Therefore, GCD of numbers 110, 858, 20, 921 is 1

Given Input Data is 110, 858, 20, 921

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

Prime Factorization of 110 is 2 x 5 x 11

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 921 is 3 x 307

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(110, 858) = 4290

GCD(110, 858) = ( 110 x 858 ) / 4290

GCD(110, 858) = 94380 / 4290

GCD(110, 858) = 22

Step2:

Here we consider the GCD from the above i.e. 22 as first number and the next as 20

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

LCM(22, 20) = 220

GCD(22, 20) = ( 22 x 20 ) / 220

GCD(22, 20) = 440 / 220

GCD(22, 20) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 921

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

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

GCD(2, 921) = 1842 / 1842

GCD(2, 921) = 1

GCD of 110, 858, 20, 921 is 1
