Given Input Data is 378, 502, 105
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7
Prime Factorization of 502 is 2 x 251
Prime Factorization of 105 is 3 x 5 x 7
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 378, 502, 105 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(378, 502) = 94878
GCD(378, 502) = ( 378 x 502 ) / 94878
GCD(378, 502) = 189756 / 94878
GCD(378, 502) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 105
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 105) = 210
GCD(2, 105) = ( 2 x 105 ) / 210
GCD(2, 105) = 210 / 210
GCD(2, 105) = 1
GCD of 378, 502, 105 is 1
