109 whole numbers greater than 9 and less than 999 are multiples of 9
4 numbers less than 70 that are multiples of 3 and 5
All nonzero numbers have an infinite amount of multiples.
The 16 whole multiples of 6 that are less than 100 are: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96. There are an infinite number of multiples of 6, because there are an infinite number of whole numbers.
-- All natural numbers. -- All integers. -- All real numbers. -- All numbers less than 32.1 . -- All positive whole numbers. -- All numbers greater than 23.9 . -- All numbers containing the digit ' 2 '. -- All even numbers (multiples of 2). -- All multiples of 4 .
the set of whole numbers less than 0
As numbers get larger, it is more likely that they will be multiples of something.
3. All other multiples of 3 are not prime.
There are 3 such numbers: 30, 60, 90.
Prime and odd numbers
The multiples of 5 that are also multiples of 6 are multiples of their LCM. The LCM of 5 and 6 is 30, so the question becomes which multiples of 30 are less than 100? The solution is the numbers: 30, 60, 90
To have a whole number square root, the number is a perfect square. Thus the numbers will be the squares of multiples of 11. Thus the first number will be (1×11) × (1×11) = 11² = 121 The next candidate will be (2×11) × (2×11) = 22² = 484 The next possible candidate will be (3×11) × (3×11) = 33² = 1089 which is too large. Thus there are two multiples of 11 less than 1000 whose square roots are whole numbers, namely 121 (11²) and 484 (22²)
