The product of two positive integers is 1000 If neither of the numbers is a multiple of 10 what is their sum?

Prime factorization of 1000 is
2 x 2 x 2 x 5 x 5 x 5
The only way to get 2 positive integers out of these factors that aren't multiples of 10 would be
{2 x 2 x 2} and {5 x 5 x 5}
or 8 and 125
So the sum would be 133.
(If we multiplied any other combination of factors, you would get a multiple of 10 due to the 5 x 2 term...)

How do signed numbers differ from integers?
Positive signed numbers with have a + Positive integers will not.
Are positive and negative numbers integers?
yes integers are all numbers negative and positive
Are there any number that are neither prime nor composite?
Yes. All prime numbers and composite numbers are positive integers, or whole counting numbers. That leaves infinitely many numbers that are neither prime nor composite. If you intended to narrow the scope of your question to the whole counting numbers or to the positive integers, then there are NO such numbers that are neither. A counting number, however large, will be either prime or composite.
Why is 1 the least positive integer?
Integers are numbers that are not followed by decimals, so they are "complete" numbers. Numbers below zero are not positive, and zero itself is neither positive nor negative, so positive integers are 1, 2, 3, 4, 5, and so on. 1 is the smallest number of these, so it is the least positive integer.
Is it true that there are no integers that are whole numbers?
No, integers are positive and negative whole numbers
Positive and negative whole numbers and zero?
Positive and negative whole numbers and zero are integers. Zero is neither negative or positive.
When do you use positive integers?
The set of natural numbers (counting numbers) {1,2,3,4....} corresponds to the positive integers. Note that the number 0 is neither positive nor negative. So anytime you want to count something you use natural numbers, which means you are also using positive integers.
are the numbers nine zero and seventeen positive integers?
9 and 17 are. Zero is neutral, neither positive nor negative.
Is every number greater than zero a positive integer?
No. Only the whole numbers greater than zero are positive integers. 1, 2, 4, 989, 589595, 1000000 are positive integers. 0.5, pi, 1.99, 1000.0001 are positive numbers but they are not positive integers. 0 is an integer, but it is neither positive nor negative.
How do signed numbers differ from integers?
Positive signed numbers with have a + Positive integers will not.
How do you compare integers with positive numbers?
Some integers are positive numbers.Some integers are not positive numbers.Some positive numbers are integers.Some positive numbers are not integers.They are two sets whose intersection is the set of counting numbers.
Is positive integers belong to natural numbers?
Positive integers are (not is!) a proper subset of natural numbers. The natural numbers comprise positive integers and zero.
Are positive and negative numbers integers?
yes integers are all numbers negative and positive
Are there any number that are neither prime nor composite?

What are integer numbers?
Integers are the positive and negative whole numbers with the addition of 0. The positive integers are the numbers 1, 2, 3, 4, 5, 6, etc. The negative integers are the numbers -1, -2, -3, -4, -5, -6, etc. 0 is neither positive or negative.any whole number that is positive, negative, or the number 0
Another name for the positive integers?
The natural numbers are the same as the positive integers.
