Greatest Common Divisior

We found the divisors of 55, 31, 63 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 55, 31, 63 is 1.

Therefore, GCD of numbers 55, 31, 63 is 1

Given Input Data is 55, 31, 63

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

Prime Factorization of 55 is 5 x 11

Prime Factorization of 31 is 31

Prime Factorization of 63 is 3 x 3 x 7

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(55, 31) = 1705

GCD(55, 31) = ( 55 x 31 ) / 1705

GCD(55, 31) = 1705 / 1705

GCD(55, 31) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 63

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

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

GCD(1, 63) = 63 / 63

GCD(1, 63) = 1

GCD of 55, 31, 63 is 1
