Question

Find the greatest number of three digits that can be exactly divided by 75, 45 and 80​

Answer 1

Answer:

3600 is the greatest 4 - digit no which is exactly divided by 75, 45 and 80​ .

Step-by-step explanation:

Here we have to find the greatest number of three digits that can be exactly divided by 75, 45, and 80​. Means find LCM and then decide.

Lets find the L.C.M

75 = 3 × 5 × 5

45 = 3 × 3 × 5

80 = 2× 2  × 2  × 2 × 5

L.C.M =  2× 2  × 2  × 2 × 3 × 3 × 5 × 5

L.C.M = 3600

So 3600 is the greatest 4 - digit no.

Hence , the greatest number of three digits that can be exactly divided by 75, 45 and 80​ is not found.
