Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 632/745,120/990
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 632,120
Greatest Common Factor of Numerators i.e. GCF of 632,120 is 8 .
LCM of Denominators means LCM of 745,990 as per the given fractions.
LCM of 745,990 is 147510 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 632,120
2 | 632, 120 |
2 | 316, 60 |
2 | 158, 30 |
79, 15 |
∴ So the GCF of the given numbers is 2 x 2 x 2 = 8

1,2,4,8,79,158,316,632
Factors of 120
List of positive integer factors of 120 that divides 120 without a remainder.
1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120
Greatest Common Factor
We found the factors 632,120 . The biggest common factor number is the GCF number.
So the greatest common factor 632,120 is 8.
Lets's calculate LCM of 745,990
5 | 745, 990 |
149, 198 |
∴ So the LCM of the given numbers is 5 x 149 x 198 = 147510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/147510
Therefore, the GCF of Fractions 632/745,120/990 is 8/147510
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 745,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(745,990) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(745,990) x common factors =5 x 1 = 5
LCM(745,990) = ( 745 × 990 ) / 5
LCM(745,990) = 737550 / 5
LCM(745,990) = 147510
