Know Least Common Multiple of fractions 505/483, 406/690, 618/861 quickly i.e. 21118090 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 505/483, 406/690, 618/861 is 21118090.
LCM(505/483, 406/690, 618/861) = 21118090
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 505/483,406/690,618/861
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 505,406,618
Least Common Multiple of Numerators i.e. LCM of 505,406,618 is 63354270.
GCF of Denominators means GCF of 483,690,861 as per the given fractions.
GCF of 483,690,861 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 505,406,618
2 | 505, 406, 618 |
505, 203, 309 |
∴ So the LCM of the given numbers is 2 x 505 x 203 x 309 = 63354270
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 505,406,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(505,406,618) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(505,406,618) x common factors =1 x 2 = 2
LCM(505,406,618) = ( 505 × 406 × 618 ) / 2
LCM(505,406,618) = 126708540 / 2
LCM(505,406,618) = 63354270
Lets's calculate GCF of 483,690,861
3 | 483, 690, 861 |
161, 230, 287 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 63354270/3
Therefore the LCM of Fractions 505/483,406/690,618/861 is 21118090
