Know Least Common Multiple of fractions 297/28, 690/4774 quickly i.e. 68310/14 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 297/28, 690/4774 is 68310/14.
LCM(297/28, 690/4774) = 68310/14
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 297/28,690/4774
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 297,690
Least Common Multiple of Numerators i.e. LCM of 297,690 is 68310.
GCF of Denominators means GCF of 28,4774 as per the given fractions.
GCF of 28,4774 is 14 as it is the largest common factor for these numbers.
Lets's calculate LCM of 297,690
3 | 297, 690 |
99, 230 |
∴ So the LCM of the given numbers is 3 x 99 x 230 = 68310
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 297,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(297,690) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(297,690) x common factors =3 x 1 = 3
LCM(297,690) = ( 297 × 690 ) / 3
LCM(297,690) = 204930 / 3
LCM(297,690) = 68310
Lets's calculate GCF of 28,4774
2 | 28, 4774 |
7 | 14, 2387 |
2, 341 |
∴ So the GCF of the given numbers is 2 x 7 = 14
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 68310/14
Therefore the LCM of Fractions 297/28,690/4774 is 68310/14
