Question

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

Answer 1

LCM of 8, 10, and 12

2 |8, 10, 12
2 |4, 5, 6
2 |2, 5, 3
3 |1, 5, 3
5 |1, 5, 1
1 ,1, 1

LCM = 2 × 2 × 2 × 3 × 5 = 120

We have to find the greatest 3-digit multiple of 120.

It can be seen that 120 ×8 = 960 and 120 × 9 = 1080.

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

I hope it's correct and helps you...
