Question

Find atleast 5 digit number which is exactly divisible by 20,25,30

Answer 1

Answer:

10,200.

Step-by-step explanation:

First, we find the L.C.M of the three numbers:

L.C.M of 20, 25, 30

= 5 × 2 × 2 × 5 × 3

= 300.

Although 300 is divisible by the three given numbers, we need a 5 digit number which must be a multiple of 300.

So, therefore we divide 10000/300:

= 10,000 ÷ 300

= 33.33

And go with the next higher number, 34.

Hence, the answer is:

= 300 × 34

= 10,200.
