Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 115/252,299/784
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 115,299
Greatest Common Factor of Numerators i.e. GCF of 115,299 is 23 .
LCM of Denominators means LCM of 252,784 as per the given fractions.
LCM of 252,784 is 7056 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 115,299
23 | 115, 299 |
5, 13 |
∴ So the GCF of the given numbers is 23 = 23
Factors of 115
List of positive integer factors of 115 that divides 115 without a remainder.
1,5,23,115
Factors of 299
List of positive integer factors of 299 that divides 299 without a remainder.
1,13,23,299
Greatest Common Factor
We found the factors 115,299 . The biggest common factor number is the GCF number.
So the greatest common factor 115,299 is 23.
Lets's calculate LCM of 252,784
2 | 252, 784 |
2 | 126, 392 |
7 | 63, 196 |
9, 28 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 9 x 28 = 7056
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/7056
Therefore, the GCF of Fractions 115/252,299/784 is 23/7056
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 252,784 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(252,784) = 28
common factors(in case of two or more numbers have common factors) = 1
GCF(252,784) x common factors =28 x 1 = 28
LCM(252,784) = ( 252 × 784 ) / 28
LCM(252,784) = 197568 / 28
LCM(252,784) = 7056
