100 is the lowest 3-digit number and it is composite, so 100 is your answer.
The lowest three digit odd number would have to be -999.However, if you mean the lowest three digit positive number, it would be 101.
-998 would have to be the lowest three digit even number. If you mean a positive number, it would be 100.
It is: 3 and 41/50 as a mixed number in its lowest terms
The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
A smaller 3 digit number or a 2 digit number (99).
The lowest three digit odd number would have to be -999.However, if you mean the lowest three digit positive number, it would be 101.
100
The diference between the highest 4 digit number and the lowest 3 digit number is 9999 Highest 4 digit: 9999 Lowest 3 digit: 000
Referring to only positive integers, the smallest composite number is 4 (2 x 2). A composite number is any number that is the product of two or more prime numbers.*Referring to all integers, it would be the negative number -9, (3 x -3), which is the also the arithmetically lowest one-digit number. However, under normal definitions, negative numbers are not considered prime or composite numbers.
999 = 3 x 333 = 9 x 111so is a composite (not prime) number.
-998 would have to be the lowest three digit even number. If you mean a positive number, it would be 100.
-1
It is a two-digit, composite natural number.
1.11 ============================= .111 is lower yet, but neither one meets the usual definition of 3-digit number. By the usual definition, 100 is the smallest 3-digit or 3 figure number.
Absolutely ! There are many solutions - the lowest is... 1999-999=1000 *Side note* Actually, the solution when looking for the lowest value of the term that still gives you a four-digit differance, has to be found in the answer of 1100 - 100 = 1000, since 100 is the - using your word- "lowest" value of a three digit-number, as well as 1000 being the "lowest" four-digit 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.
1637143983 is not prime. Its prime factorisation is: 3 × 3 × 7321 × 24847.In the case of this number and one ninth of all integers, the fact that it is composite can be quickly determined by calculating the core digit value, the sum of all digits reduced to one digit. The core digit value of this number is 9, and every single integer with this core digit value is a multiple of 9. This can only prove that a number is composite. A core digit value other than 9 does not prove that a number is prime.
