Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 96/14,72/75,720/38
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 96,72,720
Greatest Common Factor of Numerators i.e. GCF of 96,72,720 is 24 .
LCM of Denominators means LCM of 14,75,38 as per the given fractions.
LCM of 14,75,38 is 19950 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 96,72,720
2 | 96, 72, 720 |
2 | 48, 36, 360 |
2 | 24, 18, 180 |
3 | 12, 9, 90 |
4, 3, 30 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 3 = 24

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 96,72,720 . The biggest common factor number is the GCF number.
So the greatest common factor 96,72,720 is 24.
Lets's calculate LCM of 14,75,38
2 | 14, 75, 38 |
7, 75, 19 |
∴ So the LCM of the given numbers is 2 x 7 x 75 x 19 = 19950
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 24/19950
Therefore, the GCF of Fractions 96/14,72/75,720/38 is 24/19950
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 14,75,38 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,75,38) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(14,75,38) x common factors =1 x 2 = 2
LCM(14,75,38) = ( 14 × 75 × 38 ) / 2
LCM(14,75,38) = 39900 / 2
LCM(14,75,38) = 19950
