Greatest Common Divisior
We found the divisors of 407, 975, 66, 219 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 407, 975, 66, 219 is 1.
Therefore, GCD of numbers 407, 975, 66, 219 is 1
Given Input Data is 407, 975, 66, 219
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 407 is 11 x 37
Prime Factorization of 975 is 3 x 5 x 5 x 13
Prime Factorization of 66 is 2 x 3 x 11
Prime Factorization of 219 is 3 x 73
The above numbers do not have any common prime factor. So GCD is 1
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(407, 975) = 396825
GCD(407, 975) = ( 407 x 975 ) / 396825
GCD(407, 975) = 396825 / 396825
GCD(407, 975) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 66
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 66) = 66
GCD(1, 66) = ( 1 x 66 ) / 66
GCD(1, 66) = 66 / 66
GCD(1, 66) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 219
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 219) = 219
GCD(1, 219) = ( 1 x 219 ) / 219
GCD(1, 219) = 219 / 219
GCD(1, 219) = 1
GCD of 407, 975, 66, 219 is 1
