Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 58/840,13/4890
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 58,13
Greatest Common Factor of Numerators i.e. GCF of 58,13 is 1 .
LCM of Denominators means LCM of 840,4890 as per the given fractions.
LCM of 840,4890 is 136920 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 58,13
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 58
List of positive integer factors of 58 that divides 58 without a remainder.
1,2,29,58
Factors of 13
List of positive integer factors of 13 that divides 13 without a remainder.
1,13
Greatest Common Factor
We found the factors 58,13 . The biggest common factor number is the GCF number.
So the greatest common factor 58,13 is 1.
Lets's calculate LCM of 840,4890
2 | 840, 4890 |
3 | 420, 2445 |
5 | 140, 815 |
28, 163 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 28 x 163 = 136920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/136920
Therefore, the GCF of Fractions 58/840,13/4890 is 1/136920
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 840,4890 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,4890) = 30
common factors(in case of two or more numbers have common factors) = 1
GCF(840,4890) x common factors =30 x 1 = 30
LCM(840,4890) = ( 840 × 4890 ) / 30
LCM(840,4890) = 4107600 / 30
LCM(840,4890) = 136920
