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



Answer -

LCM of 8, 10 and 12

LCM = 2 × 2 × 2 × 3 × 5 = 120

Now we need to find the greatest 3-digit multiple of 120

We may find 120 × 8 = 960 and 120 × 9 = 1080

Hence, 960 is the greatest 3-digit number exactly divisible by 8, 10 and 12
