Why is it when you multiply two prime numbers you get a number with three or four factors?
If the two prime numbers are different:
You get the two prime numbers, plus 1, plus the product.
For example, if you multiply 2 x 3 = 6, the factors of 6 are 2, 3, 1, and 6.
If the two prime numbers are the same:
You get the Prime number, 1, and the product.
For example 2 x 2 = 4. The factors of 4 are 2, 1, 4.
What else can I help you with?
If multiplying 2 prime numbers will the product always be prime?
If you multiply 2 prime numbers. the result will never be prime. A prime number is one that has no factors except itself and one. The number specified in the question has as factors the 2 prime numbers cited.
How do you work out the prime factors of a number?
1. Find out which numbers multiply together to reach the target number, then find out which numbers multiply together to make the numbers that multiply together to reach the target number.
If a composite number has the first five prime numbers as factors what is the smallest number it could be?
Just multiply the first five prime numbers! 2x3x5x7x11 = 6x35x11 = 210x11 = 2310. Any multiple of this number "has the first five prime numbers as factors", but 2310 is the smallest such number.
How do you work out the product of prime factors?
Multiply prime numbers or prime factors to find their product.
What is the difference between factors of a number and prime factors of a number?
All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
When you multiply two prime numbers why will the answer not be a prime number?
When you multiply two prime numbers together they become factors of the number that they equal. Since the number will have factors other than 1 and itself, the number cannot be prime.
Will you get the same number of factors if you multiply a prime number and itself?
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
If multiplying 2 prime numbers will the product always be prime?
If you multiply 2 prime numbers. the result will never be prime. A prime number is one that has no factors except itself and one. The number specified in the question has as factors the 2 prime numbers cited.
How do you work out the prime factors of a number?
1. Find out which numbers multiply together to reach the target number, then find out which numbers multiply together to make the numbers that multiply together to reach the target number.
Are prime factors and prime factorization the same?
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
Will you get the same number of factors in 187 if you multiply two different prime numbers?
187 will have the same number of factors no matter what you do to it.
What is a step diagram for prime factors?
it is a way of finding out all of the prime numbers that you have to multiply to equal the desired number.
What number has exactly 5 different prime factors?
Take any 5 prime numbers and multiply them together.
What is an easy way to generate numbers with an odd number of factors?
Start with the factors. Multiply combinations of three prime factors, then combinations of five, then seven, etc. All generated numbers will be guaranteed to have an odd number of prime factors.
If a composite number has the first five prime numbers as factors what is the smallest number it could be?
Just multiply the first five prime numbers! 2x3x5x7x11 = 6x35x11 = 210x11 = 2310. Any multiple of this number "has the first five prime numbers as factors", but 2310 is the smallest such number.
Why are prime numbers prime?
A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
How do you work out the product of prime factors?
Multiply prime numbers or prime factors to find their product.
