Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 810/180,831/802
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 810/180,831/802, numerators are 810,831
Denominators are 180,802
The GCF of 810,831 is 3 .
LCM of 180,802 is 72180.
The greatest common factor of 810/180,831/802 = [GCF of 810,831]/[LCM of 180,802]= 3/72180
Therefore, the GCF of 810/180,831/802 is 3/72180.
To find the highest common factor of 810,831, we have to find the factors of both numbers and list the highest common factor.
The factors of 810 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
The factors of 831 are 1, 3, 277, 831
The HCF of 810,831 is 3.
Lets's calculate GCF of 810,831
3 | 810, 831 |
270, 277 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 810
:1,2,3,5,6,9,10,15,18,27,30,45,54,81,90,135,162,270,405,810
Now, list down the factors of 831
:1,3,277,831
Greatest Common Factor
We found the factors 810,831 . The biggest common factor number is the GCF number.
So the greatest common factor 810,831 is 3.
Lets's calculate LCM of 180,802
2 | 180, 802 |
90, 401 |
∴ So the LCM of the given numbers is 2 x 90 x 401 = 72180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/72180
Therefore, the GCF of Fractions 810/180,831/802 is 3/72180
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 180,802 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(180,802) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(180,802) x common factors =2 x 1 = 2
LCM(180,802) = ( 180 × 802 ) / 2
LCM(180,802) = 144360 / 2
LCM(180,802) = 72180
