Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 145/42,911/2079
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 145,911
Greatest Common Factor of Numerators i.e. GCF of 145,911 is 1 .
LCM of Denominators means LCM of 42,2079 as per the given fractions.
LCM of 42,2079 is 4158 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 145,911
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 145
List of positive integer factors of 145 that divides 145 without a remainder.
1,5,29,145
Factors of 911
List of positive integer factors of 911 that divides 911 without a remainder.
1,911
Greatest Common Factor
We found the factors 145,911 . The biggest common factor number is the GCF number.
So the greatest common factor 145,911 is 1.
Lets's calculate LCM of 42,2079
3 | 42, 2079 |
7 | 14, 693 |
2, 99 |
∴ So the LCM of the given numbers is 3 x 7 x 2 x 99 = 4158
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4158
Therefore, the GCF of Fractions 145/42,911/2079 is 1/4158
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 42,2079 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,2079) = 21
common factors(in case of two or more numbers have common factors) = 1
GCF(42,2079) x common factors =21 x 1 = 21
LCM(42,2079) = ( 42 × 2079 ) / 21
LCM(42,2079) = 87318 / 21
LCM(42,2079) = 4158
