Question

Determine the greatest 3-digit number exactly divisible by 8,10 and 12.​

Answer 1

Answer:

960

Step-by-step explanation:

Firstly we need to find the LCM of 8,10 and 12.

Using Prime Factorisation Method

8=2×2×2

10=2×5

12=2×2×3

LCM of 8,10 and 12= 2×2×2×3×5=120

120 is exactly divisible by 8,10 and 12.

Now

The greatest 3 digit number =999

999=120×8+39

Here, remainder is 39

Therefore, the greatest 3-digit number exactly divisible by 8,10 and 12 =120×8=960
