RafaOh, dude, you're hitting me with some math now? Alright, let me just casually drop this knowledge on you. So, between 400 and 600, you've got 56 numbers, and if we're talking about numbers divisible by 9, you divide the last number by 9 and the first number by 9, and then you subtract the two results. So, you end up with 66 minus 44, which gives you 22 numbers divisible by 9 in that range. Easy peasy, right?

How many numbers between 1-400 are divisible by 7?
400 / 7 = 57, so there are 57 multiples of 7 under 400.
How many numbers between 1 and 400 divisible by 3 or 7?
7x3 = 21 All numbers from 1-400 (399 total) that are factors of 21: 399/21 = 19
How many numbers are there between 301 and 400 divisible by both 3 and 4?
There are 8 numbers: 312, 324, 336, 348, 360, 372, 384, 396.
How many numbers between 400 and 800 are divisible by 13?
To find the number of integers between 400 and 800 that are divisible by 13, we first need to find the smallest and largest multiples of 13 within this range. The smallest multiple of 13 greater than or equal to 400 is 403, and the largest multiple less than or equal to 800 is 793. To find the count of numbers divisible by 13 in this range, we calculate (793-403)/13 + 1 = 31. Therefore, there are 31 numbers between 400 and 800 that are divisible by 13.
