The prime factorization of the number at the top
two- digit modifier
It is called a twelve-digit number. Its exact name will depend on the number.
55 has factors other than 1 and itself, so it is not a prime number. For example, 55 is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 55 is a composite number.composite

The prime number between 20 and 30 whose ones digit is 7 greater than its tens digit is 23. The tens digit is 2, and the ones digit is 3, which is 7 greater than 2. Additionally, 23 is a prime number because it is only divisible by 1 and itself, with no other factors.
Squares (or cubes or more) of prime numbers have one distinct prime factor, but if you're counting them individually, all composite numbers have at least two prime factors.
The prime factorization of the number at the top
A prime number is any number that only has one and itself as factors. By definition even numbers have a factor of two. Therefore the only even number that is prime is the number 2.
What is 36 single digit number
We generally refer to them by the number of digits. Two-digit number, three-digit number, etc.
A 24-digit number is called a septillion, as it consists of 24 individual numerical digits. In the context of computing, a 24-digit number can also be referred to as a "double precision" floating-point number, typically used to represent very large or very small values with high precision. In mathematics, a 24-digit number can be used to express extremely large quantities or precise measurements.
Just that - a 26-digit number. There is no special name for that.
