Greatest Common Divisior
We found the divisors of 297, 477, 15, 860 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 297, 477, 15, 860 is 1.
Therefore, GCD of numbers 297, 477, 15, 860 is 1
Given Input Data is 297, 477, 15, 860
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 477 is 3 x 3 x 53
Prime Factorization of 15 is 3 x 5
Prime Factorization of 860 is 2 x 2 x 5 x 43
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, 477) = 15741
GCD(297, 477) = ( 297 x 477 ) / 15741
GCD(297, 477) = 141669 / 15741
GCD(297, 477) = 9
Step2:
Here we consider the GCD from the above i.e. 9 as first number and the next as 15
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(9, 15) = 45
GCD(9, 15) = ( 9 x 15 ) / 45
GCD(9, 15) = 135 / 45
GCD(9, 15) = 3
Step3:
Here we consider the GCD from the above i.e. 3 as first number and the next as 860
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 860) = 2580
GCD(3, 860) = ( 3 x 860 ) / 2580
GCD(3, 860) = 2580 / 2580
GCD(3, 860) = 1
GCD of 297, 477, 15, 860 is 1
