30 50 70 because they both end in 0 and 10 is a composite number
9, 99, 999 are three.
Prime numbers have no divisibles.
8, 10, and 12 are 3 composite numbers. They are composite because they ahve more than 2 factors.
Prime numbers have only two factors. Composite numbers have more than two.
Prime numbers have two factors. Composite numbers have more than two.
Prime numbers have only 2 factors which are themselves and one whereas composite numbers have more than 2 factors
Because both numbers have more than two factors which makes them composite numbers.
it is a composite number because you can tell from the 8 that it is an even number, and even numbers can always be divided.
Without a specific range, that's an infinite list.
4, 6, 10.They are composite because they have more factors than just 1 and themselves.There are 2 types of numbers, prime and composite. Prime means it's only factors are 1 and itself, ex. 7's only factors are 1 and 7.Composite means it has more than 2 factors. A factor is a number you multiply by another number to get another. Example, 4 is composite because it's factors are 1,4, and 2.
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. 47 is prime.
Try dividing by some numbers. The larger the number, the more numbers you have to divide by. It is enough to test division by 2, and all the odd numbers up to the square root of the number. For very large numbers, this is not efficient. There are more efficient methods, but they are also more difficult to understand.
