Use our free GCF of Fractions Calculator tool to compute the GCF of 81/261, 13/224 i.e 1/58464 easily. The following is the detailed procedure to determine the greatest common factor of fractions 81/261, 13/224.
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 81/261,13/224
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 81/261,13/224, numerators are 81,13
Denominators are 261,224
The GCF of 81,13 is 1 .
LCM of 261,224 is 58464.
The greatest common factor of 81/261,13/224 = [GCF of 81,13]/[LCM of 261,224]= 1/58464
Therefore, the GCF of 81/261,13/224 is 1/58464.
To find the highest common factor of 81,13, we have to find the factors of both numbers and list the highest common factor.
The factors of 81 are 1, 3, 9, 27, 81
The factors of 13 are 1, 13
The HCF of 81,13 is 1.
Lets's calculate GCF of 81,13
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 261,224
Given numbers has no common factors except 1. So, there LCM is their product i.e 58464
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/58464
Therefore, the GCF of Fractions 81/261,13/224 is 1/58464
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 261,224 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(261,224) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(261,224) x common factors =1 x 1 = 1
LCM(261,224) = ( 261 × 224 ) / 1
LCM(261,224) = 58464 / 1
LCM(261,224) = 58464
