Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 18/186,305/480
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 18,305
Greatest Common Factor of Numerators i.e. GCF of 18,305 is 1 .
LCM of Denominators means LCM of 186,480 as per the given fractions.
LCM of 186,480 is 14880 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 18,305
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 18
List of positive integer factors of 18 that divides 18 without a remainder.
1,2,3,6,9,18
Factors of 305
List of positive integer factors of 305 that divides 305 without a remainder.
1,5,61,305
Greatest Common Factor
We found the factors 18,305 . The biggest common factor number is the GCF number.
So the greatest common factor 18,305 is 1.
Lets's calculate LCM of 186,480
2 | 186, 480 |
3 | 93, 240 |
31, 80 |
∴ So the LCM of the given numbers is 2 x 3 x 31 x 80 = 14880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/14880
Therefore, the GCF of Fractions 18/186,305/480 is 1/14880
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 186,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(186,480) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(186,480) x common factors =6 x 1 = 6
LCM(186,480) = ( 186 × 480 ) / 6
LCM(186,480) = 89280 / 6
LCM(186,480) = 14880
