Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 30/77,33/15,66/41
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 30,33,66
Greatest Common Factor of Numerators i.e. GCF of 30,33,66 is 3 .
LCM of Denominators means LCM of 77,15,41 as per the given fractions.
LCM of 77,15,41 is 47355 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 30,33,66
3 | 30, 33, 66 |
10, 11, 22 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 30
List of positive integer factors of 30 that divides 30 without a remainder.
1,2,3,5,6,10,15,30
Factors of 33
List of positive integer factors of 33 that divides 33 without a remainder.
1,3,11,33
Factors of 66
List of positive integer factors of 66 that divides 66 without a remainder.
1,2,3,6,11,22,33,66
Greatest Common Factor
We found the factors 30,33,66 . The biggest common factor number is the GCF number.
So the greatest common factor 30,33,66 is 3.
Lets's calculate LCM of 77,15,41
Given numbers has no common factors except 1. So, there LCM is their product i.e 47355
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/47355
Therefore, the GCF of Fractions 30/77,33/15,66/41 is 3/47355
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 77,15,41 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,15,41) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,15,41) x common factors =1 x 1 = 1
LCM(77,15,41) = ( 77 × 15 × 41 ) / 1
LCM(77,15,41) = 47355 / 1
LCM(77,15,41) = 47355
Here are some samples of GCF of Fractions calculations.
