15 ends with the number 5, and so therefore must be divisible by the number 5. Indeed, 15/5 = 3, so our first two factors of 15 are 5 and 3. Well, both 5 and 3 are prime numbers, so we're done. You would usually write this as 3 X 5.
The prime factorization of 15 is 3 x 5.
The prime factorization of 15 is 3 x 5.
3 x 5 = 15
To find the Least Common Multiple (LCM) of 15 and 30, we first need to find the prime factorization of each number. The prime factorization of 15 is 3 x 5, and the prime factorization of 30 is 2 x 3 x 5. To find the LCM, we take the highest power of each prime factor that appears in either number, which gives us 2 x 3 x 5 = 30. Therefore, the LCM of 15 and 30 is 30.
3 x 5 = 15
15 23
Prime Factorization of 9 and 15The prime factorization of 9 is:3 X 3The prime factorization of 15 is:3 X 5
To find the Least Common Multiple (LCM) of 12, 9, and 15, we first need to find the prime factorization of each number. The prime factorization of 12 is 2^2 * 3, the prime factorization of 9 is 3^2, and the prime factorization of 15 is 3 * 5. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2^2 * 3^2 * 5 = 180. Therefore, the LCM of 12, 9, and 15 is 180.
3 times 5 is what i got
7 is already prime. The prime factorization of 15 is 3 x 5.
Prime factorization is the process of determining all of the prime factors of a given number. Prime factors are the prime numbers that when multiplied together give you the number to be factored. For example the prime factorization of 30 is 15 x 2
