Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 970/45,142/7108
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 970,142
Greatest Common Factor of Numerators i.e. GCF of 970,142 is 2 .
LCM of Denominators means LCM of 45,7108 as per the given fractions.
LCM of 45,7108 is 319860 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 970,142
2 | 970, 142 |
485, 71 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 970
List of positive integer factors of 970 that divides 970 without a remainder.
1,2,5,10,97,194,485,970
Factors of 142
List of positive integer factors of 142 that divides 142 without a remainder.
1,2,71,142
Greatest Common Factor
We found the factors 970,142 . The biggest common factor number is the GCF number.
So the greatest common factor 970,142 is 2.
Lets's calculate LCM of 45,7108
Given numbers has no common factors except 1. So, there LCM is their product i.e 319860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/319860
Therefore, the GCF of Fractions 970/45,142/7108 is 2/319860
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 45,7108 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,7108) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(45,7108) x common factors =1 x 1 = 1
LCM(45,7108) = ( 45 × 7108 ) / 1
LCM(45,7108) = 319860 / 1
LCM(45,7108) = 319860
Here are some samples of GCF of Fractions calculations.
