Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 4/42,894/41,386/51
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 4,894,386
Greatest Common Factor of Numerators i.e. GCF of 4,894,386 is 2 .
LCM of Denominators means LCM of 42,41,51 as per the given fractions.
LCM of 42,41,51 is 29274 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 4,894,386
2 | 4, 894, 386 |
2, 447, 193 |
∴ So the GCF of the given numbers is 2 = 2

1,2,3,6,149,298,447,894
Factors of 386
List of positive integer factors of 386 that divides 386 without a remainder.
1,2,193,386
Greatest Common Factor
We found the factors 4,894,386 . The biggest common factor number is the GCF number.
So the greatest common factor 4,894,386 is 2.
Lets's calculate LCM of 42,41,51
3 | 42, 41, 51 |
14, 41, 17 |
∴ So the LCM of the given numbers is 3 x 14 x 41 x 17 = 29274
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/29274
Therefore, the GCF of Fractions 4/42,894/41,386/51 is 2/29274
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 42,41,51 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,41,51) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(42,41,51) x common factors =1 x 3 = 3
LCM(42,41,51) = ( 42 × 41 × 51 ) / 3
LCM(42,41,51) = 87822 / 3
LCM(42,41,51) = 29274
