Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 309/30,190/558
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 309,190
Greatest Common Factor of Numerators i.e. GCF of 309,190 is 1 .
LCM of Denominators means LCM of 30,558 as per the given fractions.
LCM of 30,558 is 2790 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 309,190
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 309
List of positive integer factors of 309 that divides 309 without a remainder.
1,3,103,309
Factors of 190
List of positive integer factors of 190 that divides 190 without a remainder.
1,2,5,10,19,38,95,190
Greatest Common Factor
We found the factors 309,190 . The biggest common factor number is the GCF number.
So the greatest common factor 309,190 is 1.
Lets's calculate LCM of 30,558
2 | 30, 558 |
3 | 15, 279 |
5, 93 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 93 = 2790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2790
Therefore, the GCF of Fractions 309/30,190/558 is 1/2790
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 30,558 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,558) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(30,558) x common factors =6 x 1 = 6
LCM(30,558) = ( 30 × 558 ) / 6
LCM(30,558) = 16740 / 6
LCM(30,558) = 2790
