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.
What are the first five factors of 7?
7 is a prime number. The only factors of a prime number are 1 and itself, so 7 only has two factors.
What is the smallest number that has 5 different prime factors?
To calculate this interesting number you need to use the five smallest prime numbers. A prime number is one which is not evenly divisible by any other number (except itself and 1). The first prime number is 2. then we have 3, 5, 7, 11, 13, 17 and so on. So, if you multiply 2 x 3 x 5 x 7 x 11 you'll get the smallest number with 5 different prime factors.
What are the prime factors of 105?
105 is a composite number because it has factors other than 1 and itself. It is not a prime number. The prime factorization of 105 is 3 x 5 x 7.
Is five prime or composite?
5 is a prime number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
How do you find the factors of 5?
Five has no even factors and is therefore a prime number. 5 is a prime number. Its only factors are one and itself.

What are the first five factors of 7?
7 is a prime number. The only factors of a prime number are 1 and itself, so 7 only has two factors.
Why is five a prime number?
Because it only has two factors 1 and itself. So it is a prime number
What is a prime number that is a factor 115?
Five and 23 are the two prime factors of 115.
What are five prime numbers that have three factors and what are their similarities?
There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.
What are the first five factors of 59?
59 is a prime number and therefore does not have any factors.
What is the smallest number that has 5 different prime factors?
To calculate this interesting number you need to use the five smallest prime numbers. A prime number is one which is not evenly divisible by any other number (except itself and 1). The first prime number is 2. then we have 3, 5, 7, 11, 13, 17 and so on. So, if you multiply 2 x 3 x 5 x 7 x 11 you'll get the smallest number with 5 different prime factors.
What numbers are prime to five?
5 is a prime number and has no factors other than 1 and itself.
Does five only have two factors?
Yes, 1 and 5, because 5 is a prime number. A prime number is a number that only has two factors, one and itself. 2 is the only even prime number. 1 is not a prime number or a composite number.
What is the largest 3 digit number with exactly five prime factors?
The best way to tackle this is to take the largest 3 digit number (999) and work out its prime factors. You can then work down until you get one with exactly five prime factors. 999 is 3x3x3x37, 998 is 2x499, 997 is prime, 996 is 2x2x3x83, 995 is 5x199, 994 is 2x7x71, 993 is 3x331, 992 is 2x2x2x2x2x31, 991 is prime, 990 is 2x3x3x5x11. That is the first we came across with five prime factors. Therefore the largest 3 digit number with exactly five prime factors is 990.
Is 5 a prime or composite?
The number five is a prime number because its only factors are 1 and itself. To be a composite number, a number has to have more than those two factors.
