Question

The only prime factors of a number n are 2, 5, 7, and 17, which of the following could Not be a factor of n?

Answer 1

The number in option 3 could not be a factor of n.

Step-by-step explanation:

The question asks which of the given options could not be a factor of the number n, whose only prime factors are 2, 5, 7, and 17. To determine this, we need to identify the numbers in the given options that are not divisible by any of these prime factors. Let's go through the options one by one:

1. Option 2: The number 2 is a prime factor of n, so this option could be a factor of n.
2. Option 5: The number 5 is a prime factor of n, so this option could be a factor of n.
3. Option 7: The number 7 is a prime factor of n, so this option could be a factor of n.
4. Option 3: The number 3 is not one of the prime factors of n, so this option could not be a factor of n.

Therefore, the number in option 3 could not be a factor of n.

Answer 2

It's 17 because all the numbers that make 17 up are all prime
