Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 386/25,122/4020
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 386,122
Greatest Common Factor of Numerators i.e. GCF of 386,122 is 2 .
LCM of Denominators means LCM of 25,4020 as per the given fractions.
LCM of 25,4020 is 20100 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 386,122
2 | 386, 122 |
193, 61 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 386
List of positive integer factors of 386 that divides 386 without a remainder.
1,2,193,386
Factors of 122
List of positive integer factors of 122 that divides 122 without a remainder.
1,2,61,122
Greatest Common Factor
We found the factors 386,122 . The biggest common factor number is the GCF number.
So the greatest common factor 386,122 is 2.
Lets's calculate LCM of 25,4020
5 | 25, 4020 |
5, 804 |
∴ So the LCM of the given numbers is 5 x 5 x 804 = 20100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/20100
Therefore, the GCF of Fractions 386/25,122/4020 is 2/20100
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 25,4020 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(25,4020) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(25,4020) x common factors =5 x 1 = 5
LCM(25,4020) = ( 25 × 4020 ) / 5
LCM(25,4020) = 100500 / 5
LCM(25,4020) = 20100
