Greatest Common Divisior
We found the divisors of 856, 132, 78 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 856, 132, 78 is 2.
Therefore, GCD of numbers 856, 132, 78 is 2
Given Input Data is 856, 132, 78
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 856 is 2 x 2 x 2 x 107
Prime Factorization of 132 is 2 x 2 x 3 x 11
Prime Factorization of 78 is 2 x 3 x 13
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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(856, 132) = 28248
GCD(856, 132) = ( 856 x 132 ) / 28248
GCD(856, 132) = 112992 / 28248
GCD(856, 132) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 78
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 78) = 156
GCD(4, 78) = ( 4 x 78 ) / 156
GCD(4, 78) = 312 / 156
GCD(4, 78) = 2
GCD of 856, 132, 78 is 2
