Therefore, GCD of numbers 858, 456, 684, 905 is 1

Given Input Data is 858, 456, 684, 905

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 456 is 2 x 2 x 2 x 3 x 19

Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19

Prime Factorization of 905 is 5 x 181

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, 456) = 65208

GCD(858, 456) = ( 858 x 456 ) / 65208

GCD(858, 456) = 391248 / 65208

GCD(858, 456) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 684

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

LCM(6, 684) = 684

GCD(6, 684) = ( 6 x 684 ) / 684

GCD(6, 684) = 4104 / 684

GCD(6, 684) = 6

Step3:

Here we consider the GCD from the above i.e. 6 as first number and the next as 905

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

LCM(6, 905) = 5430

GCD(6, 905) = ( 6 x 905 ) / 5430

GCD(6, 905) = 5430 / 5430

GCD(6, 905) = 1

GCD of 858, 456, 684, 905 is 1
