Given Input Data is 55, 33, 72
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 55 is 5 x 11
Prime Factorization of 33 is 3 x 11
Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 55, 33, 72 using LCM Formula
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, 33) = 165
GCD(55, 33) = ( 55 x 33 ) / 165
GCD(55, 33) = 1815 / 165
GCD(55, 33) = 11
Step2:
Here we consider the GCD from the above i.e. 11 as first number and the next as 72
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(11, 72) = 792
GCD(11, 72) = ( 11 x 72 ) / 792
GCD(11, 72) = 792 / 792
GCD(11, 72) = 1
GCD of 55, 33, 72 is 1
