42, 48, 54, and 60 is. -- If it's 'even' then it must also be divisible by 2 . -- If it's divisible by 3 and also by 2, then it must be divisible by 6 . -- The multiples of 6 between 40 and 60 are 42, 48, 54, and 60 .
If, when divided by 3, it leaves no remainder. Also, if you add the individual numbers up and that number is divisible by three, the larger one is as well. Example: 12345 adds up to 15. 15 is divisible by three. So is 12345.
All the numbers up to 100 are factors in some numbers up to 100. For example, 1 is a factor of every number and 2 is a factor of all the even numbers. The numbers greater than 50 are only factors of themselves among the numbers up to 100, 95 is only a factor of itself, because the next number for which it is a factor is 190, which is greater than 100.
Divide the number by thirteen. If the answer comes out even with no remainder, the number is divisible by thirteen.
You can do it with two (36 + 64) you can do it with three if you include zero but there aren't three distinct square numbers that add up to 100 in that range. 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
There are 14 numbers between 1 & 100 that are divisible by 7.
Any of its multiples up to 100
100 is divisible by 5. The next is 105, the next is 110, and so on forever.
The numbers divisible by nine up to a 100 are 9,18,27,36,45,54,63,72,81,90,and,99
25
Just count up all the even numbers which will all be divisible by 2
Any number ending in a 5 or 0 !
100 / 8 = 12.5. Rounding this up gives you 13, therefore 13 x 8 is the first multiple of 8 (i.e., number divisible by 8) in the desired range. After that, simply add 8 at a time to get additional multiples.
42, 48, 54, and 60 is. -- If it's 'even' then it must also be divisible by 2 . -- If it's divisible by 3 and also by 2, then it must be divisible by 6 . -- The multiples of 6 between 40 and 60 are 42, 48, 54, and 60 .
Numbers up to 200 divisible by both 2 and 3 = numbers to 200 divisible by 2*3 = 6 which is int(200/6) = int(33.33) = 33
Counting up from 1, there is a number divisible by 3 every 3 numbers. Thus to find out how many numbers are divisible by 3, we just have to divide the number we're counting to by 3. In this case, the top number is 50, so do: 50/3 = 16 with two remainder. Because the numbers divisible by 3 come last in every set of 3 numbers, we can discard the remainder. Therefore there are 16 numbers between 1 and 50 that are divisible by 3.
