Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 4/32,493/84,187/80
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 4,493,187
Greatest Common Factor of Numerators i.e. GCF of 4,493,187 is 1 .
LCM of Denominators means LCM of 32,84,80 as per the given fractions.
LCM of 32,84,80 is 3360 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 4,493,187
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 4

1,2,4
Factors of 493
List of positive integer factors of 493 that divides 493 without a remainder.
1,17,29,493
Factors of 187
List of positive integer factors of 187 that divides 187 without a remainder.
1,11,17,187
Greatest Common Factor
We found the factors 4,493,187 . The biggest common factor number is the GCF number.
So the greatest common factor 4,493,187 is 1.
Lets's calculate LCM of 32,84,80
2 | 32, 84, 80 |
2 | 16, 42, 40 |
2 | 8, 21, 20 |
2 | 4, 21, 10 |
2, 21, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 21 x 5 = 3360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3360
Therefore, the GCF of Fractions 4/32,493/84,187/80 is 1/3360
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 32,84,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,84,80) = 4
common factors(in case of two or more numbers have common factors) = 16
GCF(32,84,80) x common factors =4 x 16 = 64
LCM(32,84,80) = ( 32 × 84 × 80 ) / 64
LCM(32,84,80) = 215040 / 64
LCM(32,84,80) = 3360
