To determine the primality of a number, several algorithms can be used. How to determine whether an integer is a prime number? 100: indeed, 100 is a multiple of itself, since 100 is evenly divisible by 100 (we have 100 / 100 = 1, so the remainder of this division is indeed zero).0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 100 too, since 0 × 100 = 0.There are infinitely many multiples of 100.

The multiples of 100 are all integers evenly divisible by 100, that is all numbers such that the remainder of the division by 100 is zero. Number of digits of 100ġ00 is a number with 3 digits. The square of a number (here 100) is the result of the product of this number (100) by itself (i.e., 100 × 100) the square of 100 is sometimes called 'raising 100 to the power 2', or '100 squared'. Therefore, the square root of 100 is an integer, and as a consequence 100 is a perfect square.Īs a consequence, 10 is the square root of 100. Parity of 100ġ00 is an even number, because it is evenly divisible by 2: 100 / 2 = 50.Ī number is a perfect square (or a square number) if its square root is an integer that is to say, it is the product of an integer with itself. In fact, 100 is an abundant number 100 is strictly smaller than the sum of its proper divisors (that is 1 + 2 + 4 + 5 + 10 + 20 + 25 + 50 = 117). No, 100 is not a deficient number: to be deficient, 100 should have been such that 100 is larger than the sum of its proper divisors, i.e., the divisors of 100 without 100 itself (that is 1 + 2 + 4 + 5 + 10 + 20 + 25 + 50 = 117). The last digit of 100 is 0, so it is divisible by 5 and is therefore not prime.įor 100 to be a prime number, it would have been required that 100 has only two divisors, i.e., itself and 1. The list of all positive divisors (i.e., the list of all integers that divide 100) is as follows: 1, 2, 4, 5, 10, 20, 25, 50, 100.įor 100 to be a prime number, it would have been required that 100 has only two divisors, i.e., itself and 1.Īctually, one can immediately see that 100 cannot be prime, because 5 is one of its divisors: indeed, a number ending with 0 or 5 has necessarily 5 among its divisors. It is possible to find out using mathematical methods whether a given integer is a prime number or not.įor 100, the answer is: No, 100 is not a prime number.
