So the Greatest Common Divisior 60, 65, 42 is 1.
Therefore, GCD of numbers 60, 65, 42 is 1
Given Input Data is 60, 65, 42
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 60 is 2 x 2 x 3 x 5
Prime Factorization of 65 is 5 x 13
Prime Factorization of 42 is 2 x 3 x 7
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 60, 65, 42 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(60, 65) = 780
GCD(60, 65) = ( 60 x 65 ) / 780
GCD(60, 65) = 3900 / 780
GCD(60, 65) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 42
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 42) = 210
GCD(5, 42) = ( 5 x 42 ) / 210
GCD(5, 42) = 210 / 210
GCD(5, 42) = 1
GCD of 60, 65, 42 is 1
