It will take four: 2 x 5 x 5 x 5
Six twos.
1597 is already prime and has only one prime factor.
Yes, 2x3x5 is a prime factorization because it has prime numbers multiplied to give a number. It is the prime factorization of 30.
17 times 2 !
They are: 1*31 = 31 which is a prime number
301 is a prime number. Therefore only two numbers multiplied together to give 301 is itself and 1.
3 multiplied by 3 = 9 Apart from 9 and 1, no other whole numbers give that result when multiplied.
Prime numbers are numbers that can only be multiplied by 1 and itself (whole numbers only) to give the same result 49 (7x7) and 81 (9x9) are not a prime number (perfect squares actually) 111 and 97 are a prime number (find me two numbers that gives the same product without using the number 1)
The factors of 511 are the numbers that can be multiplied together to give 511. The factors of 511 are 1, 7, 73, and 511. Prime factors are the factors that are prime numbers. The prime factors of 511 are 7 and 73, as they are the prime numbers that can be multiplied together to give 511.
Prime factors of 56 First, what two numbers multiplied give you 56? 7 x 8 Is either of these a prime number?? Yes, 7 is prime. What about 8? What two numbers multiplied together give you 8? 2 x 4 Is either of these a prime number?? Yes, 2 is prime. What about 4? What two numbers multiplied together give you 4? 2 x 2 Is either of these a prime number?? Yes, both are prime. Combining our individual results, the prime factorisation of 56 is 7 x 2 x 2 x 2
3,5and11
Obviously, the answer is a composite number. Reason:A number multiplied by another number (besides 1) will give a result of a composite number. If a number is multiplied by 0, the answer will be 0 (which is not a prime number nor composite) unless a number has been added or subtracted to give either a negative or positive number, respectively.
