We found the divisors of 400, 139, 93, 806 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 400, 139, 93, 806 is 1.

Therefore, GCD of numbers 400, 139, 93, 806 is 1

Given Input Data is 400, 139, 93, 806

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

Prime Factorization of 400 is 2 x 2 x 2 x 2 x 5 x 5

Prime Factorization of 139 is 139

Prime Factorization of 93 is 3 x 31

Prime Factorization of 806 is 2 x 13 x 31

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(400, 139) = 55600

GCD(400, 139) = ( 400 x 139 ) / 55600

GCD(400, 139) = 55600 / 55600

GCD(400, 139) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 93

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

LCM(1, 93) = 93

GCD(1, 93) = ( 1 x 93 ) / 93

GCD(1, 93) = 93 / 93

GCD(1, 93) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 806

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

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

GCD(1, 806) = 806 / 806

GCD(1, 806) = 1

GCD of 400, 139, 93, 806 is 1
