To find the factors of 1800 that are multiples of 10, we first need to factorize 1800. The prime factorization of 1800 is 2^3 * 3^2 * 5^2. To get factors that are multiples of 10, we need to include at least one factor of 2 and one factor of 5 in each factor. This means we can choose from the exponents of 2 and 5 to create factors: (2^1 * 5^1), (2^2 * 5^1), and (2^3 * 5^1), giving us 3 factors of 1800 that are multiples of 10.

Interesting.

Factors of 180: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180.

[ (ten times) each of these ] is a factor of 1,800 = 18 factors

Plus, from the list above, we can also pick 10, 20, 30, 60, 90 and 180 = 6 more factors

Total = 24 factors

No.


Of the 13 multiples of 10 which has the largest number of factors?

This is a nonsensical question. There are more than 13 multiples of 10 - in fact there are an infinite number. And there are multiples of 10 which have an infinite number of factors - so there cannot be a "largest" number of factors.


What is multiples of 5 and10 called?

Multiples of 5 and 10 are called common multiples.


What multiples of 10 are factors of 280?

To find the multiples of 10 that are factors of 280, we need to identify the factors of 280 first. The factors of 280 are 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, and 280. Among these factors, the multiples of 10 are 10, 20, 40, 70, and 140. Therefore, the multiples of 10 that are factors of 280 are 10, 20, 40, 70, and 140.


What has factors 2 and 5?

There are infinetly many numbers which have 2 and 5 as their factors. Some examples are 10, 20, 30, 40, etc. 2 and 5 both are prime numbers and their common multiples are the multiples of 2 x 5 = 10. So all the multiples of 10 have 2 and 5 as their factors. However if consider 2 and 5 as the only two proper factors, then the required number is 10.

How are factors and multiples the same?

No. A factor is a number or algebraic expression by which another is exactly divisible. A multiple is a number that can be divided by another number without a remainder. Factors go into numbers, numbers go into multiples.

What is a factor of 10 but not multiple of 5?

Factors of 10: 1, 10, 2, 5 Multiples of 5: 5, 10, 15, etc. From this, we see that 5 and 10 are factors of 10 and multiples of 5. Therefore, there are two numbers that are factors of 10 but not 5. They are: 1 and 2
