Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 386/47,138/119
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 386,138
Greatest Common Factor of Numerators i.e. GCF of 386,138 is 2 .
LCM of Denominators means LCM of 47,119 as per the given fractions.
LCM of 47,119 is 5593 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 386,138
2 | 386, 138 |
193, 69 |
∴ 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 138
List of positive integer factors of 138 that divides 138 without a remainder.
1,2,3,6,23,46,69,138
Greatest Common Factor
We found the factors 386,138 . The biggest common factor number is the GCF number.
So the greatest common factor 386,138 is 2.
Lets's calculate LCM of 47,119
Given numbers has no common factors except 1. So, there LCM is their product i.e 5593
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/5593
Therefore, the GCF of Fractions 386/47,138/119 is 2/5593
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 47,119 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,119) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(47,119) x common factors =1 x 1 = 1
LCM(47,119) = ( 47 × 119 ) / 1
LCM(47,119) = 5593 / 1
LCM(47,119) = 5593
