Know Least Common Multiple of fractions 792/77, 990/3456 quickly i.e. 3960 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 792/77, 990/3456 is 3960.
LCM(792/77, 990/3456) = 3960
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 792/77,990/3456
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 792,990
Least Common Multiple of Numerators i.e. LCM of 792,990 is 3960.
GCF of Denominators means GCF of 77,3456 as per the given fractions.
GCF of 77,3456 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 792,990
2 | 792, 990 |
3 | 396, 495 |
3 | 132, 165 |
11 | 44, 55 |
4, 5 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 4 x 5 = 3960
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 792,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(792,990) = 198
common factors(in case of two or more numbers have common factors) = 1
GCF(792,990) x common factors =198 x 1 = 198
LCM(792,990) = ( 792 × 990 ) / 198
LCM(792,990) = 784080 / 198
LCM(792,990) = 3960
Lets's calculate GCF of 77,3456
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3960/1
Therefore the LCM of Fractions 792/77,990/3456 is 3960
