Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 13/461,39/285
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 13/461,39/285, numerators are 13,39
Denominators are 461,285
The GCF of 13,39 is 13 .
LCM of 461,285 is 131385.
The greatest common factor of 13/461,39/285 = [GCF of 13,39]/[LCM of 461,285]= 13/131385
Therefore, the GCF of 13/461,39/285 is 13/131385.
To find the highest common factor of 13,39, we have to find the factors of both numbers and list the highest common factor.
The factors of 13 are 1, 13
The factors of 39 are 1, 3, 13, 39
The HCF of 13,39 is 13.
Lets's calculate GCF of 13,39
13 | 13, 39 |
1, 3 |
∴ So the GCF of the given numbers is 13 = 13
Lets's calculate LCM of 461,285
Given numbers has no common factors except 1. So, there LCM is their product i.e 131385
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/131385
Therefore, the GCF of Fractions 13/461,39/285 is 13/131385
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 461,285 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(461,285) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(461,285) x common factors =1 x 1 = 1
LCM(461,285) = ( 461 × 285 ) / 1
LCM(461,285) = 131385 / 1
LCM(461,285) = 131385
