Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 68/90,71/15,714/47
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 68,71,714
Greatest Common Factor of Numerators i.e. GCF of 68,71,714 is 1 .
LCM of Denominators means LCM of 90,15,47 as per the given fractions.
LCM of 90,15,47 is 4230 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 68,71,714
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 68
List of positive integer factors of 68 that divides 68 without a remainder.
1,2,4,17,34,68
Factors of 71
List of positive integer factors of 71 that divides 71 without a remainder.
1,71
Factors of 714
List of positive integer factors of 714 that divides 714 without a remainder.
1,2,3,6,7,14,17,21,34,42,51,102,119,238,357,714
Greatest Common Factor
We found the factors 68,71,714 . The biggest common factor number is the GCF number.
So the greatest common factor 68,71,714 is 1.
Lets's calculate LCM of 90,15,47
3 | 90, 15, 47 |
5 | 30, 5, 47 |
6, 1, 47 |
∴ So the LCM of the given numbers is 3 x 5 x 6 x 1 x 47 = 4230
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4230
Therefore, the GCF of Fractions 68/90,71/15,714/47 is 1/4230
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 90,15,47 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,15,47) = 1
common factors(in case of two or more numbers have common factors) = 15
GCF(90,15,47) x common factors =1 x 15 = 15
LCM(90,15,47) = ( 90 × 15 × 47 ) / 15
LCM(90,15,47) = 63450 / 15
LCM(90,15,47) = 4230
