Question

Which is largest 3 digit number that exactly divisible by 25 ​

Answer 1

Answer:

15=3×5.

25=5×5.

30=2×3×5.

L.C.M. of 15 , 25 and 30=3×5×2×5 = 150

Largest 3 digit number = 999.

Now 999÷150=6.66

Thus , the required 3 digit largest number exactly divisible by 15 ,25 and 30

= 150×6 =900

Answer 2

Answer:

975 is the largest 3 digit number which is exactly divisible by 25.

Step-by-step explanation:

Given number is 25.

 The largest 3 digit number divisible by 25 is 975.

 To know whether 975 is divisible by 25 or not.

Check by divisibility rule:

      Dividend = Divisor × quotient + remainder

   For a,b ∈ Z there exist q,r ∈ Z such that a = bq+r  where

   If a is divisible by b then r = 0

   If a is not divisible by b then r ≠ 0

    975 = 25×39 +0

    So,

    975 is the largest 3 digit number which is exactly divisible by 25.
