Whatever isn't prime:
4, 6, 8, 9, 10, 12, 14, 15, 16, 18
They are: 4 6 8 9 10 12 14 15 16 and 18 because each of them has more than 2 factors
Prime numbers have two factors. Composite have more than two. Neither (one and zero) have less than two.
Prime numbers have two factors. Composite numbers have more than two.
dont know dont care
They are both composite numbers because they have more than two factors
Julia is incorrect. 2 is an even prime number and 9 is an odd composite number.
They are: 4 6 8 9 10 12 14 15 18 and 20 because they all have more than two factors.
They are: 4 6 8 9 10 12 14 15 16 and 18 because each of them has more than 2 factors
Prime numbers have two factors. Composite have more than two. Neither (one and zero) have less than two.
The composite numbers in that list are 22 and 36 - you know they are composite, because they are even numbers. The other numbers are odd and prime.
Prime numbers have two factors. Composite numbers have more than two.
dont know dont care
Not that I know of.
I can check them for divisibility by prime numbers.
First, you have to know the difference between Prime Numbers and Composite Numbers. Prime Numbers are numbers that has only two factors: 1 and itself. Composite Numbers are numbers that have factors other than 1 and itself. Composite numbers are always even, with only one exception: number 2. Two is the ONLY EVEN PRIME NUMBER. Never will you encounter another even prime number because it will always have AT LEAST 3 factors. # ITSELF. # ONE. # TWO. Now that we know the difference between Prime and Composite, we can answer your question. 4,567,278 is an even number. It is divisible by itself, one, two and probably more numbers. Therefore, it is COMPOSITE!
4, 6, 8, 9, 10, 12, 14, 15, 16, 18 They all have more than two factors.
They are both composite numbers because they have more than two factors
