Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 86/83,43/72,55/19
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 86,43,55
Greatest Common Factor of Numerators i.e. GCF of 86,43,55 is 1 .
LCM of Denominators means LCM of 83,72,19 as per the given fractions.
LCM of 83,72,19 is 113544 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 86,43,55
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 86
List of positive integer factors of 86 that divides 86 without a remainder.
1,2,43,86
Factors of 43
List of positive integer factors of 43 that divides 43 without a remainder.
1,43
Factors of 55
List of positive integer factors of 55 that divides 55 without a remainder.
1,5,11,55
Greatest Common Factor
We found the factors 86,43,55 . The biggest common factor number is the GCF number.
So the greatest common factor 86,43,55 is 1.
Lets's calculate LCM of 83,72,19
Given numbers has no common factors except 1. So, there LCM is their product i.e 113544
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/113544
Therefore, the GCF of Fractions 86/83,43/72,55/19 is 1/113544
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 83,72,19 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,72,19) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(83,72,19) x common factors =1 x 1 = 1
LCM(83,72,19) = ( 83 × 72 × 19 ) / 1
LCM(83,72,19) = 113544 / 1
LCM(83,72,19) = 113544
Here are some samples of GCF of Fractions calculations.
