Know Least Common Multiple of fractions 72/30, 898/15, 792/631 quickly i.e. 355608 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 72/30, 898/15, 792/631 is 355608.
LCM(72/30, 898/15, 792/631) = 355608
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 72/30,898/15,792/631
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 72,898,792
Least Common Multiple of Numerators i.e. LCM of 72,898,792 is 355608.
GCF of Denominators means GCF of 30,15,631 as per the given fractions.
GCF of 30,15,631 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 72,898,792
2 | 72, 898, 792 |
2 | 36, 449, 396 |
2 | 18, 449, 198 |
3 | 9, 449, 99 |
3 | 3, 449, 33 |
1, 449, 11 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 1 x 449 x 11 = 355608
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 72,898,792 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,898,792) = 2
common factors(in case of two or more numbers have common factors) = 72
GCF(72,898,792) x common factors =2 x 72 = 144
LCM(72,898,792) = ( 72 × 898 × 792 ) / 144
LCM(72,898,792) = 51207552 / 144
LCM(72,898,792) = 355608
Lets's calculate GCF of 30,15,631
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 355608/1
Therefore the LCM of Fractions 72/30,898/15,792/631 is 355608
