Know Least Common Multiple of fractions 72/56, 86/50, 784/444 quickly i.e. 151704 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 72/56, 86/50, 784/444 is 151704.
LCM(72/56, 86/50, 784/444) = 151704
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 72/56,86/50,784/444
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 72,86,784
Least Common Multiple of Numerators i.e. LCM of 72,86,784 is 303408.
GCF of Denominators means GCF of 56,50,444 as per the given fractions.
GCF of 56,50,444 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 72,86,784
2 | 72, 86, 784 |
2 | 36, 43, 392 |
2 | 18, 43, 196 |
9, 43, 98 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 9 x 43 x 98 = 303408
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 72,86,784 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,86,784) = 2
common factors(in case of two or more numbers have common factors) = 8
GCF(72,86,784) x common factors =2 x 8 = 16
LCM(72,86,784) = ( 72 × 86 × 784 ) / 16
LCM(72,86,784) = 4854528 / 16
LCM(72,86,784) = 303408
Lets's calculate GCF of 56,50,444
2 | 56, 50, 444 |
28, 25, 222 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 303408/2
Therefore the LCM of Fractions 72/56,86/50,784/444 is 151704
