Therefore, GCD of numbers 858, 477, 497, 540 is 1

Given Input Data is 858, 477, 497, 540

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 477 is 3 x 3 x 53

Prime Factorization of 497 is 7 x 71

Prime Factorization of 540 is 2 x 2 x 3 x 3 x 3 x 5

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, 477) = 136422

GCD(858, 477) = ( 858 x 477 ) / 136422

GCD(858, 477) = 409266 / 136422

GCD(858, 477) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 497

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

LCM(3, 497) = 1491

GCD(3, 497) = ( 3 x 497 ) / 1491

GCD(3, 497) = 1491 / 1491

GCD(3, 497) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 540

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

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

GCD(1, 540) = 540 / 540

GCD(1, 540) = 1

GCD of 858, 477, 497, 540 is 1
