Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 16/30,24/60,32/75,36/120
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 16,24,32,36
Greatest Common Factor of Numerators i.e. GCF of 16,24,32,36 is 4 .
LCM of Denominators means LCM of 30,60,75,120 as per the given fractions.
LCM of 30,60,75,120 is 600 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 16,24,32,36
2 | 16, 24, 32, 36 |
2 | 8, 12, 16, 18 |
4, 6, 8, 9 |
∴ So the GCF of the given numbers is 2 x 2 = 4

1,2,3,4,6,9,12,18,36
Greatest Common Factor
We found the factors 16,24,32,36 . The biggest common factor number is the GCF number.
So the greatest common factor 16,24,32,36 is 4.
Lets's calculate LCM of 30,60,75,120
2 | 30, 60, 75, 120 |
2 | 15, 30, 75, 60 |
3 | 15, 15, 75, 30 |
5 | 5, 5, 25, 10 |
1, 1, 5, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 1 x 1 x 5 x 2 = 600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/600
Therefore, the GCF of Fractions 16/30,24/60,32/75,36/120 is 4/600
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 30,60,75,120 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,60,75,120) = 15
common factors(in case of two or more numbers have common factors) = 1800
GCF(30,60,75,120) x common factors =15 x 1800 = 27000
LCM(30,60,75,120) = ( 30 × 60 × 75 × 120 ) / 27000
LCM(30,60,75,120) = 16200000 / 27000
LCM(30,60,75,120) = 600
