43 is a 2 digit odd number but it is a prime number
The greatest two-digit composite number would be 99, since 99 can be divided by 11, 9, and 3. I you look around this number, you will see why: 98 is also a composite number, but it is smaller than 99. 100 is also a composite number, but it has three digits. 97 has two digits, but it is a prime number. On the other hand, 99 divided by 11= 9, 99 divided by 9= 11, and 99 divided by 3=33.
10 = 2 x 5
11 is the smallest 2-digit prime number and 97 is the greatest 2 digit prime number, so their difference is 86
Six.
The largest 2 digit composite number is 99.
To be an even number then the final digit = 2. The largest single prime digit is 7 (as both 8 and 9 are composite). The greatest even number fulfilling the conditions is 77777772.
42 is composite, 43 is prime.
28 is an example of a 2 digit composite number because it has more than two factors.
well, it's not 999 because that's odd ... can't see why it wouldn't be 998, which is the greatest even three-digit number, and since all even numbers besides 2 are composite, it must also be the greatest three-digit composite even number
Since the greatest digit is 9 and the greatest 2-digit number is 99, the product of them is 891.
The greatest 2-digit even number is 98
2 digit number
Work back from 999:999 is odd ... no.998 is even and divisible by 2, so it is composite. (All even numbers are composite!)Further Information:-All even numbers are composite except for 2 which is a prime number.
