Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 163/84,489/1300
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 163,489
Greatest Common Factor of Numerators i.e. GCF of 163,489 is 163 .
LCM of Denominators means LCM of 84,1300 as per the given fractions.
LCM of 84,1300 is 27300 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 163,489
163 | 163, 489 |
1, 3 |
∴ So the GCF of the given numbers is 163 = 163
Factors of 163
List of positive integer factors of 163 that divides 163 without a remainder.
1,163
Factors of 489
List of positive integer factors of 489 that divides 489 without a remainder.
1,3,163,489
Greatest Common Factor
We found the factors 163,489 . The biggest common factor number is the GCF number.
So the greatest common factor 163,489 is 163.
Lets's calculate LCM of 84,1300
2 | 84, 1300 |
2 | 42, 650 |
21, 325 |
∴ So the LCM of the given numbers is 2 x 2 x 21 x 325 = 27300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 163/27300
Therefore, the GCF of Fractions 163/84,489/1300 is 163/27300
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 84,1300 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,1300) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(84,1300) x common factors =4 x 1 = 4
LCM(84,1300) = ( 84 × 1300 ) / 4
LCM(84,1300) = 109200 / 4
LCM(84,1300) = 27300
