Know Least Common Multiple of fractions 783/14, 790/4000 quickly i.e. 309285 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 783/14, 790/4000 is 309285.
LCM(783/14, 790/4000) = 309285
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 783/14,790/4000
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 783,790
Least Common Multiple of Numerators i.e. LCM of 783,790 is 618570.
GCF of Denominators means GCF of 14,4000 as per the given fractions.
GCF of 14,4000 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 783,790
Given numbers has no common factors except 1. So, there LCM is their product i.e 618570
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 783,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(783,790) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(783,790) x common factors =1 x 1 = 1
LCM(783,790) = ( 783 × 790 ) / 1
LCM(783,790) = 618570 / 1
LCM(783,790) = 618570
Lets's calculate GCF of 14,4000
2 | 14, 4000 |
7, 2000 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 618570/2
Therefore the LCM of Fractions 783/14,790/4000 is 309285
