Given:

After subtraction of a certain number from the number 6846, the result will be completely divisible by 6, 8, and 12. We have to find a certain number.

Concept Used:

Concept of LCM

Calculation:

6 = 2 × 3

8 = 2 × 2 × 2

12 = 2 × 2 × 3

LCM of 6, 8 and 12 is 2 × 2 × 3 × 2 = 24

Now, dividing 6846 by 24 get the quotient = 285 and the remainder = 6

Thus, it is clear that if we subtract 6 from the number 6846 the result will be completely divisible by 24

⇒ (6846 - 6) = 6840 will be completely divisible by 24

⇒ 6840 will be completely divisible by 6, 8 and 12

∴ The required least number is 6.
