Question

determine the smallest three digit number which is exactly divisible by 6,8 &12?.

Answer 1

The very first step you have to do is take the LCM of the 3 numbers which is 24. The least number of these 3 digits is 100(100 is the smallest 3 digit number). So 100/24 is 4.16 which is rounded to 4. The equation for this is 100+(24-4) which gives 120. Therefore the smallest 3 digit number which is exactly equal to 6,8 and 12 is 120.

Answer 2

Answer:

120

Step-by-step explanation:

LCM (6,8,12)

2|6 8 12.

2|3 4 6

3|3 2 3

2|1 2 1

|1 1 1

2×2×2×3

=120

smallest 3-digit number = 100

5.

24| 100

120

4×24 =96

5×24 = 120

• required number = 120
