Know Least Common Multiple of fractions 280/61, 154/42, 784/174 quickly i.e. 43120 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 280/61, 154/42, 784/174 is 43120.
LCM(280/61, 154/42, 784/174) = 43120
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 280/61,154/42,784/174
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 280,154,784
Least Common Multiple of Numerators i.e. LCM of 280,154,784 is 43120.
GCF of Denominators means GCF of 61,42,174 as per the given fractions.
GCF of 61,42,174 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 280,154,784
2 | 280, 154, 784 |
2 | 140, 77, 392 |
2 | 70, 77, 196 |
7 | 35, 77, 98 |
5, 11, 14 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 5 x 11 x 14 = 43120
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 280,154,784 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(280,154,784) = 14
common factors(in case of two or more numbers have common factors) = 56
GCF(280,154,784) x common factors =14 x 56 = 784
LCM(280,154,784) = ( 280 × 154 × 784 ) / 784
LCM(280,154,784) = 33806080 / 784
LCM(280,154,784) = 43120
Lets's calculate GCF of 61,42,174
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 43120/1
Therefore the LCM of Fractions 280/61,154/42,784/174 is 43120
