Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 58/74,40/39,10/78
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 58,40,10
Greatest Common Factor of Numerators i.e. GCF of 58,40,10 is 2 .
LCM of Denominators means LCM of 74,39,78 as per the given fractions.
LCM of 74,39,78 is 2886 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 58,40,10
2 | 58, 40, 10 |
29, 20, 5 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 58
List of positive integer factors of 58 that divides 58 without a remainder.
1,2,29,58
Factors of 40
List of positive integer factors of 40 that divides 40 without a remainder.
1,2,4,5,8,10,20,40
Factors of 10
List of positive integer factors of 10 that divides 10 without a remainder.
1,2,5,10
Greatest Common Factor
We found the factors 58,40,10 . The biggest common factor number is the GCF number.
So the greatest common factor 58,40,10 is 2.
Lets's calculate LCM of 74,39,78
2 | 74, 39, 78 |
3 | 37, 39, 39 |
13 | 37, 13, 13 |
37, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 37 x 1 x 1 = 2886
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2886
Therefore, the GCF of Fractions 58/74,40/39,10/78 is 2/2886
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 74,39,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,39,78) = 1
common factors(in case of two or more numbers have common factors) = 78
GCF(74,39,78) x common factors =1 x 78 = 78
LCM(74,39,78) = ( 74 × 39 × 78 ) / 78
LCM(74,39,78) = 225108 / 78
LCM(74,39,78) = 2886
