Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 43/657,215/379
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 43,215
Greatest Common Factor of Numerators i.e. GCF of 43,215 is 43 .
LCM of Denominators means LCM of 657,379 as per the given fractions.
LCM of 657,379 is 249003 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 43,215
43 | 43, 215 |
1, 5 |
∴ So the GCF of the given numbers is 43 = 43
Factors of 43
List of positive integer factors of 43 that divides 43 without a remainder.
1,43
Factors of 215
List of positive integer factors of 215 that divides 215 without a remainder.
1,5,43,215
Greatest Common Factor
We found the factors 43,215 . The biggest common factor number is the GCF number.
So the greatest common factor 43,215 is 43.
Lets's calculate LCM of 657,379
Given numbers has no common factors except 1. So, there LCM is their product i.e 249003
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 43/249003
Therefore, the GCF of Fractions 43/657,215/379 is 43/249003
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 657,379 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(657,379) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(657,379) x common factors =1 x 1 = 1
LCM(657,379) = ( 657 × 379 ) / 1
LCM(657,379) = 249003 / 1
LCM(657,379) = 249003
Here are some samples of GCF of Fractions calculations.
