Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 99/243,369/186
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 99,369
Greatest Common Factor of Numerators i.e. GCF of 99,369 is 9 .
LCM of Denominators means LCM of 243,186 as per the given fractions.
LCM of 243,186 is 15066 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 99,369
3 | 99, 369 |
3 | 33, 123 |
11, 41 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Factors of 99
List of positive integer factors of 99 that divides 99 without a remainder.
1,3,9,11,33,99
Factors of 369
List of positive integer factors of 369 that divides 369 without a remainder.
1,3,9,41,123,369
Greatest Common Factor
We found the factors 99,369 . The biggest common factor number is the GCF number.
So the greatest common factor 99,369 is 9.
Lets's calculate LCM of 243,186
3 | 243, 186 |
81, 62 |
∴ So the LCM of the given numbers is 3 x 81 x 62 = 15066
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/15066
Therefore, the GCF of Fractions 99/243,369/186 is 9/15066
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 243,186 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(243,186) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(243,186) x common factors =3 x 1 = 3
LCM(243,186) = ( 243 × 186 ) / 3
LCM(243,186) = 45198 / 3
LCM(243,186) = 15066
