21, for example.
It is 99 which is a composite number because it has more than two factors
4 is the least one digit composite number
10 = 2 x 5
Yes, 43 is a two-digit odd number because it has two digits and is not divisible by 2. It is a prime number because it can only be divided by 1 and itself. A composite number is a positive integer greater than 1 that has at least one positive divisor other than 1 and itself, so 43 is not a composite number.
The ratio of the number of one-digit prime numbers to the number of one-digit composite numbers is one to one. The one-digit prime numbers are 2, 3, 5, and 7. The one-digit composite numbers are 4, 6, 8, and 9. Therefor, the ratio is 4:4, which simplifies to 1:1.
The largest 2 digit composite number is 99.
42 is composite, 43 is prime.
28 is an example of a 2 digit composite number because it has more than two factors.
10
How about 99
The last digit is a 2 which implies that the number is divisible by 2. So 46832 is not prime, it is composite.
How about 99
It is 99 which is a composite number because it has more than two factors
yesAny even number (except 2) is a composite number. You can identify an even number by the last digit. If the last digit is even (0, 2, 4, 6, or 8), the entire number is even.
least two-digit composite number = 11
4 is the least one digit composite number
10 = 2 x 5
