In other words, if two numbers are multiplied together and result in 17, then the numbers are the factors of 17. As 17 is a prime number, it has only two factors, such as 1 and the number itself. Hence, the factors of 17 are 1 and 17.

Multiples of 17 are 17, 34, 51, 68, 85, 102, 119, 136, 153. The multiples of a number are obtained by multiplying the number by another number. Multiples are commonly discussed in the context of integers.

With this example you may notice there is only one set of factor pairs, this is because 17 is a prime number, which can only be divided by itself and 1.

The LCM of 7 and 17 is 119. To find the LCM (least common multiple) of 7 and 17, we need to find the multiples of 7 and 17 (multiples of 7 = 7, 14, 21, 28 . . . . 119; multiples of 17 = 17, 34, 51, 68 . . . . 119) and choose the smallest multiple that is exactly divisible by 7 and 17, i.e., 119.

Factors of 17 are numbers that, when multiplied in pairs give the product as 17. There are overall 2 factors of 17 i.e. 1 and 17 where 17 is the biggest factor. The sum of all factors of 17 is 18. Its Prime Factors is 1, 17 and (1, 17) are Pair Factors.

For example, 3 and 5, 5 and 7, 11 and 13, and 17 and 19 are twin primes. As numbers get larger, primes become less frequent and twin primes rarer still.

Number 17 is prime because it doesn't have proper factors. In other words, the only factors of 17 are 1 and itself. To be sure of it, we can use the following property. If 𝒏 is a natural number, and neither of the prime numbers is less than divides 𝒏, then 𝒏 is a prime number.

When we compare the two lists to see what they have in common, we get the answer to "What are the common multiples of 4 and 17?" 68, 136, 204, 272, etc. Since 68 is the first number they have in common, 68 is the least common multiple of 4 and 17.
