Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 66/725,720/115
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 66,720
Greatest Common Factor of Numerators i.e. GCF of 66,720 is 6 .
LCM of Denominators means LCM of 725,115 as per the given fractions.
LCM of 725,115 is 16675 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 66,720
2 | 66, 720 |
3 | 33, 360 |
11, 120 |
∴ So the GCF of the given numbers is 2 x 3 = 6

1,2,3,4,5,6,8,9,10,12,15,16,18,20,24,30,36,40,45,48,60,72,80,90,120,144,180,240,360,720
Greatest Common Factor
We found the factors 66,720 . The biggest common factor number is the GCF number.
So the greatest common factor 66,720 is 6.
Lets's calculate LCM of 725,115
5 | 725, 115 |
145, 23 |
∴ So the LCM of the given numbers is 5 x 145 x 23 = 16675
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/16675
Therefore, the GCF of Fractions 66/725,720/115 is 6/16675
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 725,115 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(725,115) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(725,115) x common factors =5 x 1 = 5
LCM(725,115) = ( 725 × 115 ) / 5
LCM(725,115) = 83375 / 5
LCM(725,115) = 16675
