Greatest Common Divisior

We found the divisors of 90, 31, 49, 93 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 90, 31, 49, 93 is 1.

Therefore, GCD of numbers 90, 31, 49, 93 is 1

Given Input Data is 90, 31, 49, 93

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

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 31 is 31

Prime Factorization of 49 is 7 x 7

Prime Factorization of 93 is 3 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(90, 31) = 2790

GCD(90, 31) = ( 90 x 31 ) / 2790

GCD(90, 31) = 2790 / 2790

GCD(90, 31) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 49

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

LCM(1, 49) = 49

GCD(1, 49) = ( 1 x 49 ) / 49

GCD(1, 49) = 49 / 49

GCD(1, 49) = 1

Step3:

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

GCD of 90, 31, 49, 93 is 1
