Know Least Common Multiple of fractions 7/99, 9/72, 42/55, 22/930 quickly i.e. 1386 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 7/99, 9/72, 42/55, 22/930 is 1386.
LCM(7/99, 9/72, 42/55, 22/930) = 1386
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 7/99,9/72,42/55,22/930
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 7,9,42,22
Least Common Multiple of Numerators i.e. LCM of 7,9,42,22 is 1386.
GCF of Denominators means GCF of 99,72,55,930 as per the given fractions.
GCF of 99,72,55,930 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 7,9,42,22
2 | 7, 9, 42, 22 |
3 | 7, 9, 21, 11 |
7 | 7, 3, 7, 11 |
1, 3, 1, 11 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 3 x 1 x 11 = 1386
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 7,9,42,22 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7,9,42,22) = 1
common factors(in case of two or more numbers have common factors) = 42
GCF(7,9,42,22) x common factors =1 x 42 = 42
LCM(7,9,42,22) = ( 7 × 9 × 42 × 22 ) / 42
LCM(7,9,42,22) = 58212 / 42
LCM(7,9,42,22) = 1386
Lets's calculate GCF of 99,72,55,930
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1386/1
Therefore the LCM of Fractions 7/99,9/72,42/55,22/930 is 1386
