Know Least Common Multiple of fractions 75/42, 12/794, 970/240 quickly i.e. 14550 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 75/42, 12/794, 970/240 is 14550.
LCM(75/42, 12/794, 970/240) = 14550
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 75/42,12/794,970/240
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 75,12,970
Least Common Multiple of Numerators i.e. LCM of 75,12,970 is 29100.
GCF of Denominators means GCF of 42,794,240 as per the given fractions.
GCF of 42,794,240 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 75,12,970
2 | 75, 12, 970 |
3 | 75, 6, 485 |
5 | 25, 2, 485 |
5, 2, 97 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 5 x 2 x 97 = 29100
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 75,12,970 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(75,12,970) = 1
common factors(in case of two or more numbers have common factors) = 30
GCF(75,12,970) x common factors =1 x 30 = 30
LCM(75,12,970) = ( 75 × 12 × 970 ) / 30
LCM(75,12,970) = 873000 / 30
LCM(75,12,970) = 29100
Lets's calculate GCF of 42,794,240
2 | 42, 794, 240 |
21, 397, 120 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 29100/2
Therefore the LCM of Fractions 75/42,12/794,970/240 is 14550
