What is the smallest number with nineteen factors?
240 is the smallest number with at least 19 factors. 240 has twenty factors: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240 262144 is the smallest number with EXACTLY 19 factors
What is the smallest number with 15 factors?
It is actually 144
What number between 300 and 400 exactly has 15 factors?
This number would have to be a squared number as it only has 15 factors. The number I have calculated is 324 as the square root is 18
Which number has exactly 15 factors?
The number that has exactly 15 factors is 28. To determine the number of factors a number has, you can prime factorize the number and then add 1 to each exponent in the prime factorization and multiply these numbers together. In the case of 28, the prime factorization is 2^2 * 7^1, so the number of factors is (2+1) * (1+1) = 3 * 2 = 6. To have exactly 15 factors, the number needs to be a square of a prime number, so 28 = 2^2 * 7^1 fits this criteria.
What number is composite 15 17 19 0r 23?
15 has more than exactly two factors (1, 3, 5, and 15), therefore it is composite. 17, 19, and 23 each have exactly 2 factors (1 and the number itself), so they are primes.

What is the only number with exactly 15 factors?
Any prime number to the 14th power, like 16384.
Common factors of 11 and 15?
Factors are numbers which divide another number exactly. The factors of 11 are 1 and 11. The factors of 15 are 1, 3, 5 and 15. So the only common factor of 11 and 15 is 1.
What is the smallest number that is divisible by 20 and 15?
The smallest number that is divisible by 20 and 15 is 60.
