Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 343/57,721/7225
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 343,721
Greatest Common Factor of Numerators i.e. GCF of 343,721 is 7 .
LCM of Denominators means LCM of 57,7225 as per the given fractions.
LCM of 57,7225 is 411825 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 343,721
7 | 343, 721 |
49, 103 |
∴ So the GCF of the given numbers is 7 = 7
Factors of 343
List of positive integer factors of 343 that divides 343 without a remainder.
1,7,49,343
Factors of 721
List of positive integer factors of 721 that divides 721 without a remainder.
1,7,103,721
Greatest Common Factor
We found the factors 343,721 . The biggest common factor number is the GCF number.
So the greatest common factor 343,721 is 7.
Lets's calculate LCM of 57,7225
Given numbers has no common factors except 1. So, there LCM is their product i.e 411825
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/411825
Therefore, the GCF of Fractions 343/57,721/7225 is 7/411825
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 57,7225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,7225) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(57,7225) x common factors =1 x 1 = 1
LCM(57,7225) = ( 57 × 7225 ) / 1
LCM(57,7225) = 411825 / 1
LCM(57,7225) = 411825
