Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 409/100,309/900
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 409/100,309/900, numerators are 409,309
Denominators are 100,900
The GCF of 409,309 is 1 .
LCM of 100,900 is 900.
The greatest common factor of 409/100,309/900 = [GCF of 409,309]/[LCM of 100,900]= 1/900
Therefore, the GCF of 409/100,309/900 is 1/900.
To find the highest common factor of 409,309, we have to find the factors of both numbers and list the highest common factor.
The factors of 409 are 1, 409
The factors of 309 are 1, 3, 103, 309
The HCF of 409,309 is 1.
Lets's calculate GCF of 409,309
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 409
:1,409
Now, list down the factors of 309
:1,3,103,309
Greatest Common Factor
We found the factors 409,309 . The biggest common factor number is the GCF number.
So the greatest common factor 409,309 is 1.
Lets's calculate LCM of 100,900
2 | 100, 900 |
2 | 50, 450 |
5 | 25, 225 |
5 | 5, 45 |
1, 9 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 5 x 1 x 9 = 900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/900
Therefore, the GCF of Fractions 409/100,309/900 is 1/900
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 100,900 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(100,900) = 100
common factors(in case of two or more numbers have common factors) = 1
GCF(100,900) x common factors =100 x 1 = 100
LCM(100,900) = ( 100 × 900 ) / 100
LCM(100,900) = 90000 / 100
LCM(100,900) = 900
