Given Input Data is 120, 630, 671
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 120 is 2 x 2 x 2 x 3 x 5
Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7
Prime Factorization of 671 is 11 x 61
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 120, 630, 671 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(120, 630) = 2520
GCD(120, 630) = ( 120 x 630 ) / 2520
GCD(120, 630) = 75600 / 2520
GCD(120, 630) = 30
Step2:
Here we consider the GCD from the above i.e. 30 as first number and the next as 671
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(30, 671) = 20130
GCD(30, 671) = ( 30 x 671 ) / 20130
GCD(30, 671) = 20130 / 20130
GCD(30, 671) = 1
GCD of 120, 630, 671 is 1
