Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 63/157,84/120
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 63,84
Greatest Common Factor of Numerators i.e. GCF of 63,84 is 21 .
LCM of Denominators means LCM of 157,120 as per the given fractions.
LCM of 157,120 is 18840 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 63,84
3 | 63, 84 |
7 | 21, 28 |
3, 4 |
∴ So the GCF of the given numbers is 3 x 7 = 21
Factors of 63
List of positive integer factors of 63 that divides 63 without a remainder.
1,3,7,9,21,63
Factors of 84
List of positive integer factors of 84 that divides 84 without a remainder.
1,2,3,4,6,7,12,14,21,28,42,84
Greatest Common Factor
We found the factors 63,84 . The biggest common factor number is the GCF number.
So the greatest common factor 63,84 is 21.
Lets's calculate LCM of 157,120
Given numbers has no common factors except 1. So, there LCM is their product i.e 18840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/18840
Therefore, the GCF of Fractions 63/157,84/120 is 21/18840
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 157,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(157,120) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(157,120) x common factors =1 x 1 = 1
LCM(157,120) = ( 157 × 120 ) / 1
LCM(157,120) = 18840 / 1
LCM(157,120) = 18840
Here are some samples of GCF of Fractions calculations.
