What is a four digit number divisible by 4 and 9?

Answer 1

Well, honey, a four-digit number divisible by both 4 and 9 is any number that is divisible by the least common multiple of 4 and 9, which is 36. So, any four-digit number that ends in 36 would fit the bill. Hope that clears things up for ya!

Answer 2

Oh, what a happy little question! A four-digit number that is divisible by both 4 and 9 is like a beautiful painting coming to life. Let's create one together: 4320. It's divisible by 4 because the last two digits are divisible by 4, and it's divisible by 9 because the sum of its digits is also divisible by 9. Just like painting, math can be a joyful experience when we approach it with a calm and positive mindset.

Answer 3

Any number to be divisible by 4 and 9 must be a multiple of their lowest common multiple; lcm(4, 9) = 36. Thus:

First 4 digit number is 1000 → 1000 ÷ 36 = 27 7/9 → first multiple of 36 which is a 4 digit number is 28 × 36 (= 1008);

Last 4 digit number is 9999 → 9999 ÷ 36 = 277 3/4 → last multiple of 36 which is a 4 digit number is 277 × 36 (= 9972);

Thus all multiples of 36 between 28 and 277 (inclusive) are four digit numbers divisible by both 4 and 9, namely:

Take your pick to select "a number divisible by 4 and 9".

Answer 4

A four-digit number divisible by both 4 and 9 must be divisible by their least common multiple, which is 36. To find a four-digit number divisible by 36, we look for multiples of 36 in the range of 1000 to 9999. The smallest four-digit number divisible by 36 is 1008 (28 x 36 = 1008).
