Greatest Common Divisior
We found the divisors of 679, 408, 72, 578 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 679, 408, 72, 578 is 1.
Therefore, GCD of numbers 679, 408, 72, 578 is 1
Given Input Data is 679, 408, 72, 578
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 679 is 7 x 97
Prime Factorization of 408 is 2 x 2 x 2 x 3 x 17
Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3
Prime Factorization of 578 is 2 x 17 x 17
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(679, 408) = 277032
GCD(679, 408) = ( 679 x 408 ) / 277032
GCD(679, 408) = 277032 / 277032
GCD(679, 408) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 72
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
GCD(1, 72) = 72 / 72
GCD(1, 72) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 578
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 578) = 578
GCD(1, 578) = ( 1 x 578 ) / 578
GCD(1, 578) = 578 / 578
GCD(1, 578) = 1
GCD of 679, 408, 72, 578 is 1
