Greatest Common Divisior
We found the divisors of 615, 492, 645 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 615, 492, 645 is 3.
Therefore, GCD of numbers 615, 492, 645 is 3
Given Input Data is 615, 492, 645
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 615 is 3 x 5 x 41
Prime Factorization of 492 is 2 x 2 x 3 x 41
Prime Factorization of 645 is 3 x 5 x 43
Highest common occurrences in the given inputs are 31
Multiplying them we get the GCD as 3
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(615, 492) = 2460
GCD(615, 492) = ( 615 x 492 ) / 2460
GCD(615, 492) = 302580 / 2460
GCD(615, 492) = 123
Step2:
Here we consider the GCD from the above i.e. 123 as first number and the next as 645
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(123, 645) = 26445
GCD(123, 645) = ( 123 x 645 ) / 26445
GCD(123, 645) = 79335 / 26445
GCD(123, 645) = 3
GCD of 615, 492, 645 is 3
