Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 43/28,10/71,387/868
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 43,10,387
Greatest Common Factor of Numerators i.e. GCF of 43,10,387 is 1 .
LCM of Denominators means LCM of 28,71,868 as per the given fractions.
LCM of 28,71,868 is 61628 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 43,10,387
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 43
List of positive integer factors of 43 that divides 43 without a remainder.
1,43
Factors of 10
List of positive integer factors of 10 that divides 10 without a remainder.
1,2,5,10
Factors of 387
List of positive integer factors of 387 that divides 387 without a remainder.
1,3,9,43,129,387
Greatest Common Factor
We found the factors 43,10,387 . The biggest common factor number is the GCF number.
So the greatest common factor 43,10,387 is 1.
Lets's calculate LCM of 28,71,868
2 | 28, 71, 868 |
2 | 14, 71, 434 |
7 | 7, 71, 217 |
1, 71, 31 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 1 x 71 x 31 = 61628
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/61628
Therefore, the GCF of Fractions 43/28,10/71,387/868 is 1/61628
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 28,71,868 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,71,868) = 1
common factors(in case of two or more numbers have common factors) = 28
GCF(28,71,868) x common factors =1 x 28 = 28
LCM(28,71,868) = ( 28 × 71 × 868 ) / 28
LCM(28,71,868) = 1725584 / 28
LCM(28,71,868) = 61628
