Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 91/45,82/70,747/300
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 91,82,747
Greatest Common Factor of Numerators i.e. GCF of 91,82,747 is 1 .
LCM of Denominators means LCM of 45,70,300 as per the given fractions.
LCM of 45,70,300 is 6300 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 91,82,747
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 91
List of positive integer factors of 91 that divides 91 without a remainder.
1,7,13,91
Factors of 82
List of positive integer factors of 82 that divides 82 without a remainder.
1,2,41,82
Factors of 747
List of positive integer factors of 747 that divides 747 without a remainder.
1,3,9,83,249,747
Greatest Common Factor
We found the factors 91,82,747 . The biggest common factor number is the GCF number.
So the greatest common factor 91,82,747 is 1.
Lets's calculate LCM of 45,70,300
2 | 45, 70, 300 |
3 | 45, 35, 150 |
5 | 15, 35, 50 |
3, 7, 10 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 7 x 10 = 6300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6300
Therefore, the GCF of Fractions 91/45,82/70,747/300 is 1/6300
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 45,70,300 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,70,300) = 5
common factors(in case of two or more numbers have common factors) = 30
GCF(45,70,300) x common factors =5 x 30 = 150
LCM(45,70,300) = ( 45 × 70 × 300 ) / 150
LCM(45,70,300) = 945000 / 150
LCM(45,70,300) = 6300
