Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 4/80,787/64,871/39
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 4,787,871
Greatest Common Factor of Numerators i.e. GCF of 4,787,871 is 1 .
LCM of Denominators means LCM of 80,64,39 as per the given fractions.
LCM of 80,64,39 is 12480 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 4,787,871
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 4
List of positive integer factors of 4 that divides 4 without a remainder.
1,2,4
Factors of 787
List of positive integer factors of 787 that divides 787 without a remainder.
1,787
Factors of 871
List of positive integer factors of 871 that divides 871 without a remainder.
1,13,67,871
Greatest Common Factor
We found the factors 4,787,871 . The biggest common factor number is the GCF number.
So the greatest common factor 4,787,871 is 1.
Lets's calculate LCM of 80,64,39
2 | 80, 64, 39 |
2 | 40, 32, 39 |
2 | 20, 16, 39 |
2 | 10, 8, 39 |
5, 4, 39 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 4 x 39 = 12480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12480
Therefore, the GCF of Fractions 4/80,787/64,871/39 is 1/12480
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 80,64,39 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,64,39) = 1
common factors(in case of two or more numbers have common factors) = 16
GCF(80,64,39) x common factors =1 x 16 = 16
LCM(80,64,39) = ( 80 × 64 × 39 ) / 16
LCM(80,64,39) = 199680 / 16
LCM(80,64,39) = 12480
