Know Least Common Multiple of fractions 820/768, 9489/987 quickly i.e. 2593660 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 820/768, 9489/987 is 2593660.
LCM(820/768, 9489/987) = 2593660
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 820/768,9489/987
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 820,9489
Least Common Multiple of Numerators i.e. LCM of 820,9489 is 7780980.
GCF of Denominators means GCF of 768,987 as per the given fractions.
GCF of 768,987 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 820,9489
Given numbers has no common factors except 1. So, there LCM is their product i.e 7780980
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 820,9489 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,9489) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(820,9489) x common factors =1 x 1 = 1
LCM(820,9489) = ( 820 × 9489 ) / 1
LCM(820,9489) = 7780980 / 1
LCM(820,9489) = 7780980
Lets's calculate GCF of 768,987
3 | 768, 987 |
256, 329 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7780980/3
Therefore the LCM of Fractions 820/768,9489/987 is 2593660
