Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 45/400,843/802
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 45,843
Greatest Common Factor of Numerators i.e. GCF of 45,843 is 3 .
LCM of Denominators means LCM of 400,802 as per the given fractions.
LCM of 400,802 is 160400 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 45,843
3 | 45, 843 |
15, 281 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 45
List of positive integer factors of 45 that divides 45 without a remainder.
1,3,5,9,15,45
Factors of 843
List of positive integer factors of 843 that divides 843 without a remainder.
1,3,281,843
Greatest Common Factor
We found the factors 45,843 . The biggest common factor number is the GCF number.
So the greatest common factor 45,843 is 3.
Lets's calculate LCM of 400,802
2 | 400, 802 |
200, 401 |
∴ So the LCM of the given numbers is 2 x 200 x 401 = 160400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/160400
Therefore, the GCF of Fractions 45/400,843/802 is 3/160400
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 400,802 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(400,802) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(400,802) x common factors =2 x 1 = 2
LCM(400,802) = ( 400 × 802 ) / 2
LCM(400,802) = 320800 / 2
LCM(400,802) = 160400
