Know Least Common Multiple of fractions 29/781, 87/244, 144/428 quickly i.e. 4176 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 29/781, 87/244, 144/428 is 4176.
LCM(29/781, 87/244, 144/428) = 4176
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 29/781,87/244,144/428
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 29,87,144
Least Common Multiple of Numerators i.e. LCM of 29,87,144 is 4176.
GCF of Denominators means GCF of 781,244,428 as per the given fractions.
GCF of 781,244,428 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 29,87,144
3 | 29, 87, 144 |
29 | 29, 29, 48 |
1, 1, 48 |
∴ So the LCM of the given numbers is 3 x 29 x 1 x 1 x 48 = 4176
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 29,87,144 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,87,144) = 1
common factors(in case of two or more numbers have common factors) = 87
GCF(29,87,144) x common factors =1 x 87 = 87
LCM(29,87,144) = ( 29 × 87 × 144 ) / 87
LCM(29,87,144) = 363312 / 87
LCM(29,87,144) = 4176
Lets's calculate GCF of 781,244,428
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4176/1
Therefore the LCM of Fractions 29/781,87/244,144/428 is 4176
