Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 60/7,63/9
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 60,63
Greatest Common Factor of Numerators i.e. GCF of 60,63 is 3 .
LCM of Denominators means LCM of 7,9 as per the given fractions.
LCM of 7,9 is 63 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 60,63
3 | 60, 63 |
20, 21 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 60
List of positive integer factors of 60 that divides 60 without a remainder.
1,2,3,4,5,6,10,12,15,20,30,60
Factors of 63
List of positive integer factors of 63 that divides 63 without a remainder.
1,3,7,9,21,63
Greatest Common Factor
We found the factors 60,63 . The biggest common factor number is the GCF number.
So the greatest common factor 60,63 is 3.
Lets's calculate LCM of 7,9
Given numbers has no common factors except 1. So, there LCM is their product i.e 63
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/63
Therefore, the GCF of Fractions 60/7,63/9 is 3/63
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 7,9 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7,9) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(7,9) x common factors =1 x 1 = 1
LCM(7,9) = ( 7 × 9 ) / 1
LCM(7,9) = 63 / 1
LCM(7,9) = 63
Here are some samples of GCF of Fractions calculations.
