Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 90/418,49/7415
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 90,49
Greatest Common Factor of Numerators i.e. GCF of 90,49 is 1 .
LCM of Denominators means LCM of 418,7415 as per the given fractions.
LCM of 418,7415 is 3099470 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 90,49
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 90
List of positive integer factors of 90 that divides 90 without a remainder.
1,2,3,5,6,9,10,15,18,30,45,90
Factors of 49
List of positive integer factors of 49 that divides 49 without a remainder.
1,7,49
Greatest Common Factor
We found the factors 90,49 . The biggest common factor number is the GCF number.
So the greatest common factor 90,49 is 1.
Lets's calculate LCM of 418,7415
Given numbers has no common factors except 1. So, there LCM is their product i.e 3099470
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3099470
Therefore, the GCF of Fractions 90/418,49/7415 is 1/3099470
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 418,7415 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(418,7415) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(418,7415) x common factors =1 x 1 = 1
LCM(418,7415) = ( 418 × 7415 ) / 1
LCM(418,7415) = 3099470 / 1
LCM(418,7415) = 3099470
Here are some samples of GCF of Fractions calculations.
