Greatest Common Divisior
We found the divisors of 66, 630, 228, 390 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 66, 630, 228, 390 is 6.
Therefore, GCD of numbers 66, 630, 228, 390 is 6
Given Input Data is 66, 630, 228, 390
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 66 is 2 x 3 x 11
Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7
Prime Factorization of 228 is 2 x 2 x 3 x 19
Prime Factorization of 390 is 2 x 3 x 5 x 13
Highest common occurrences in the given inputs are 21 x 31
Multiplying them we get the GCD as 6
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(66, 630) = 6930
GCD(66, 630) = ( 66 x 630 ) / 6930
GCD(66, 630) = 41580 / 6930
GCD(66, 630) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 228
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 228) = 228
GCD(6, 228) = ( 6 x 228 ) / 228
GCD(6, 228) = 1368 / 228
GCD(6, 228) = 6
Step3:
Here we consider the GCD from the above i.e. 6 as first number and the next as 390
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 390) = 390
GCD(6, 390) = ( 6 x 390 ) / 390
GCD(6, 390) = 2340 / 390
GCD(6, 390) = 6
GCD of 66, 630, 228, 390 is 6
