Know Least Common Multiple of fractions 97/44, 84/17, 90/85, 72/153 quickly i.e. 244440 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 97/44, 84/17, 90/85, 72/153 is 244440.
LCM(97/44, 84/17, 90/85, 72/153) = 244440
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 97/44,84/17,90/85,72/153
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 97,84,90,72
Least Common Multiple of Numerators i.e. LCM of 97,84,90,72 is 244440.
GCF of Denominators means GCF of 44,17,85,153 as per the given fractions.
GCF of 44,17,85,153 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 97,84,90,72
2 | 97, 84, 90, 72 |
2 | 97, 42, 45, 36 |
3 | 97, 21, 45, 18 |
3 | 97, 7, 15, 6 |
97, 7, 5, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 97 x 7 x 5 x 2 = 244440
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 97,84,90,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,84,90,72) = 1
common factors(in case of two or more numbers have common factors) = 216
GCF(97,84,90,72) x common factors =1 x 216 = 216
LCM(97,84,90,72) = ( 97 × 84 × 90 × 72 ) / 216
LCM(97,84,90,72) = 52799040 / 216
LCM(97,84,90,72) = 244440
Lets's calculate GCF of 44,17,85,153
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 244440/1
Therefore the LCM of Fractions 97/44,84/17,90/85,72/153 is 244440
