Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 81/13,95/13,31/949
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 81,95,31
Greatest Common Factor of Numerators i.e. GCF of 81,95,31 is 1 .
LCM of Denominators means LCM of 13,13,949 as per the given fractions.
LCM of 13,13,949 is 949 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 81,95,31
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 81
List of positive integer factors of 81 that divides 81 without a remainder.
1,3,9,27,81
Factors of 95
List of positive integer factors of 95 that divides 95 without a remainder.
1,5,19,95
Factors of 31
List of positive integer factors of 31 that divides 31 without a remainder.
1,31
Greatest Common Factor
We found the factors 81,95,31 . The biggest common factor number is the GCF number.
So the greatest common factor 81,95,31 is 1.
Lets's calculate LCM of 13,13,949
13 | 13, 13, 949 |
1, 1, 73 |
∴ So the LCM of the given numbers is 13 x 1 x 1 x 73 = 949
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/949
Therefore, the GCF of Fractions 81/13,95/13,31/949 is 1/949
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 13,13,949 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,13,949) = 13
common factors(in case of two or more numbers have common factors) = 13
GCF(13,13,949) x common factors =13 x 13 = 169
LCM(13,13,949) = ( 13 × 13 × 949 ) / 169
LCM(13,13,949) = 160381 / 169
LCM(13,13,949) = 949
