Greatest Common Divisior
We found the divisors of 297, 208, 28, 660 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 297, 208, 28, 660 is 1.
Therefore, GCD of numbers 297, 208, 28, 660 is 1
Given Input Data is 297, 208, 28, 660
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 297 is 3 x 3 x 3 x 11
Prime Factorization of 208 is 2 x 2 x 2 x 2 x 13
Prime Factorization of 28 is 2 x 2 x 7
Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11
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(297, 208) = 61776
GCD(297, 208) = ( 297 x 208 ) / 61776
GCD(297, 208) = 61776 / 61776
GCD(297, 208) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
GCD(1, 28) = 28 / 28
GCD(1, 28) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 660
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
GCD(1, 660) = 660 / 660
GCD(1, 660) = 1
GCD of 297, 208, 28, 660 is 1
