How do you find the prime number of a number?
A prime number cannot have any number multiplied to make that number, except for one. example: 9 is not prime because 3 times 3 is 9.
What is the least common multiple of 9 and 21 and 16?
To find the least common multiple (LCM) of 9, 21, and 16, we first need to find the prime factorization of each number. The prime factorization of 9 is 3^2, 21 is 3 * 7, and 16 is 2^4. To calculate the LCM, we take the highest power of each prime factor that appears in any of the numbers: 2^4 * 3^2 * 7 = 504. Therefore, the least common multiple of 9, 21, and 16 is 504.

Why is number 9 a prime number?
Actually, 9 is NOT a prime number.
If 9 is subtracted from two-thirds of a number the result is 7. Find the number.?
⅔ a number - 9 = 7 → ⅔ a number = 7 + 9 = 16 → the number is 16 × 3/2 = 24.
What is a prime number and how do to find them?
To find a prime number. #1. If an even number (ending in 0,2,4,6,8,) it is NOT a prime number. It is a composite with a factor of '2' #2. An ODD Number ending in '5' is NOT a prime number., It is a composite of '5' #3. If the digits of an ODD number sum to '9' , then it is NOT a prime number, It is a composite of '9' #4. To test for a prime number, divide by '3' & '7' , if there is a remainder to either division it is a prime number. The answer MUST NOT be a whole number. Then it is possible prime number. e.g. 839 #1. NOt EVEN #2 . Does NOT end in '5' #3. The digits sum to 8+3+9 = 20 (Does not divide by ;9;) #4. 839/3 = 279 remainder '2' or 839/7 = 119 remainder '6' So 839 is a prime number.
What number has its prime factor as 9?
9 is not a prime number.
How did you find that 71 is a prime number?
Its square root is less than 9, but it is not evenly divisible by any number less than 9, other than 1, so it is a prime number
