Know Least Common Multiple of fractions 47/56, 46/46, 24/68, 160/64 quickly i.e. 259440 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 47/56, 46/46, 24/68, 160/64 is 259440.
LCM(47/56, 46/46, 24/68, 160/64) = 259440
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 47/56,46/46,24/68,160/64
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 47,46,24,160
Least Common Multiple of Numerators i.e. LCM of 47,46,24,160 is 518880.
GCF of Denominators means GCF of 56,46,68,64 as per the given fractions.
GCF of 56,46,68,64 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 47,46,24,160
2 | 47, 46, 24, 160 |
2 | 47, 23, 12, 80 |
2 | 47, 23, 6, 40 |
47, 23, 3, 20 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 47 x 23 x 3 x 20 = 518880
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 47,46,24,160 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,46,24,160) = 1
common factors(in case of two or more numbers have common factors) = 16
GCF(47,46,24,160) x common factors =1 x 16 = 16
LCM(47,46,24,160) = ( 47 × 46 × 24 × 160 ) / 16
LCM(47,46,24,160) = 8302080 / 16
LCM(47,46,24,160) = 518880
Lets's calculate GCF of 56,46,68,64
2 | 56, 46, 68, 64 |
28, 23, 34, 32 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 518880/2
Therefore the LCM of Fractions 47/56,46/46,24/68,160/64 is 259440
