Why do prime numbers seem to get less frequent?
As numbers get larger, it is more likely that they will be multiples of something.
Which of the multiples of five are less than 100 are also multiples of six?
There are 3 such numbers: 30, 60, 90.
When is the product of two nonzero integers less than or equal of the two factors?
When one of the numbers is positive and the other is negative.
How are the numbers 16 and 32 similar?
-- both are positive numbers -- both are greater than 15 -- both are less than 1 googol -- both are even numbers -- both are written with one odd digit and one even digit -- both are powers of 2 -- both have the factors (are multiples of) 1, 2, 4, 8, and 16
How many whole numbers less than 50 are divisible by 5 or 7 but not both?
14. Assuming dealing with only counting numbers (ie integers greater than 0): Numbers divisible by 5 or 7 are their multiples. 50 ÷ 5 = 10 → last multiple of 5 less than 50 is 9 x 5 → 9 numbers less than 50 are divisible by 5 50 ÷ 7 = 71/7 → last multiple of 7 less than 50 is 7 x 7 → 7 numbers less than 50 are divisible by 7 Numbers divisible by both are those which are multiples of their lowest common multiple = 35 50 ÷ 35 = 115/35 → last multiple of 35 less than 50 is 1 x 35 → 1 number less than 50 is divisible by both 5 and 7 and needs to be removed from both the above counts. → (9 - 1) + (7 - 1) = 14 numbers less than 50 are divisible by 5 or 7 but not both. If there is no restriction on numbers being greater than 0, there are infinitely many numbers as it includes the infinite number of negative numbers which are all less than 50 and provide an infinite number of numbers divisible by 5 or 7 but not both.
What two numbers have the most multiples less than 100?
All nonzero numbers have an infinite amount of multiples.
Greta picks two numbers from a bag both numbers are square numbers both numbers are less than 100 both numbers are multiples of 8 what numbers does greta pick?
Squares numbers are positive numbers. So that the square numbers less than 100 are 1, 4, 9, 16, 25, 36, 49, 64, and 81, and only 16 and 64 are multiples of 8. Thus, Greta picked 16, and 64.
How many positive integers less than 1000 are multiples of 5 and equal to 9 times an even integer?
There are eleven such numbers.Get the common multiple of those numbers. All other common multiples will be multiples of this common multiple; that is, you can multiply the common multiple by 1, by 2, by 3, etc. to get additional numbers that are multiples of both numbers.
What is four numbers less than 70 that are multiples of both 3 and 5?
15, 30, 45, 60

What prime numbers are less than 200 and are multiples of 3?
3. All other multiples of 3 are not prime.
Which of the multiples of five are less than 100 are also multiples of six?
There are 3 such numbers: 30, 60, 90.
When is the product of two nonzero integers less than or equal of the two factors?

What set of numbers does -5 belongs?
Prime and odd numbers
Which of the multiples of 5 that are less than 100 are also multiples of 6?
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
