Given Input Data is 142, 103, 155
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 142 is 2 x 71
Prime Factorization of 103 is 103
Prime Factorization of 155 is 5 x 31
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 142, 103, 155 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(142, 103) = 14626
GCD(142, 103) = ( 142 x 103 ) / 14626
GCD(142, 103) = 14626 / 14626
GCD(142, 103) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 155
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
GCD(1, 155) = 155 / 155
GCD(1, 155) = 1
GCD of 142, 103, 155 is 1
