Question

Find the L.C.M. of 72/150 , 126/75 and 162/165

Answer 1

ANSWER:

answer is above in the picture

Answer 2

Answer:

The LCM of given is $\frac{79002}{5}$.

According to the question,

Given Data:

$\frac{72}{150}$ ,$\frac{126}{75}$ and $\frac{162}{165}.$

To Find:

To Calculate the least common multiple

Step 1:

$\frac{72}{150} = \frac{38}{75}$

$\frac{126}{75} = \frac{42}{25}$

$\frac{162}{165} = \frac{54}{55}$

Step 2:

Now LCM 0f (75, 25, 55) = 825

$\frac{38}{75} \times {825}$ = 418

$\frac{42}{25} \times 825$ = 1386

Step 3:

$\frac{54}{55} \times 825$ = 810

Now LCM ( 418,1386,810) = 13035330

Step 4:

Result:

Therefore LCM $(\frac{72}{150}, \frac{126}{75}) = \frac{13035330}{825} = 15800.4 = \frac{158004}{10} = \frac{79002}{5}$.
