Greatest Common Divisior
We found the divisors of 243, 672, 56, 100 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 243, 672, 56, 100 is 1.
Therefore, GCD of numbers 243, 672, 56, 100 is 1
Given Input Data is 243, 672, 56, 100
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3
Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7
Prime Factorization of 56 is 2 x 2 x 2 x 7
Prime Factorization of 100 is 2 x 2 x 5 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(243, 672) = 54432
GCD(243, 672) = ( 243 x 672 ) / 54432
GCD(243, 672) = 163296 / 54432
GCD(243, 672) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 56
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 56) = 168
GCD(3, 56) = ( 3 x 56 ) / 168
GCD(3, 56) = 168 / 168
GCD(3, 56) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 100
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
GCD(1, 100) = 100 / 100
GCD(1, 100) = 1
GCD of 243, 672, 56, 100 is 1
