Know Least Common Multiple of fractions 640/65, 523/53, 489/917 quickly i.e. 163678080 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 640/65, 523/53, 489/917 is 163678080.
LCM(640/65, 523/53, 489/917) = 163678080
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 640/65,523/53,489/917
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 640,523,489
Least Common Multiple of Numerators i.e. LCM of 640,523,489 is 163678080.
GCF of Denominators means GCF of 65,53,917 as per the given fractions.
GCF of 65,53,917 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 640,523,489
Given numbers has no common factors except 1. So, there LCM is their product i.e 163678080
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 640,523,489 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,523,489) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(640,523,489) x common factors =1 x 1 = 1
LCM(640,523,489) = ( 640 × 523 × 489 ) / 1
LCM(640,523,489) = 163678080 / 1
LCM(640,523,489) = 163678080
Lets's calculate GCF of 65,53,917
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 163678080/1
Therefore the LCM of Fractions 640/65,523/53,489/917 is 163678080
