Study Notes
The Number 1
The number 1, also known as one, is a small positive integer, the first of all the positive integers. It is the natural number following 0 and preceding 2. The number 1 is the smallest prime number, and it is the smallest positive integer that is not divisible by any positive integer other than 1 and itself.
Prime Number
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The number 1 is not considered a prime number because it is divisible by 1. However, 1 is the smallest prime number, as it is the only positive integer that is not divisible by any positive integers other than 1 and itself.
Divisibility
The number 1 has a unique property in the realm of divisibility. A number is divisible by 1 if and only if it is equal to 1. This means that every number is divisible by 1, but there are no other numbers that a number can be divisible by, except for 1.
Multiples
The multiples of 1 are all positive integers that can be obtained by multiplying 1 by any positive integer. For example, the multiples of 1 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and so on.
Powers
The number 1 is the base of the number system used in mathematics and science. In this number system, any positive integer can be expressed as a power of 1, where the exponent is the place value of the integer. For example, the number 123 can be expressed as 1^3 * 1^2 * 1^1, which is equal to 1 * 1 * 1, or simply 1^3.
Factorization
The number 1 has a unique factorization in the form of 1^n, where n is a positive integer. This means that the number 1 can be expressed as a product of n identical 1s, where n is any positive integer. For example, the factorization of 1 is 1^1, and the factorization of 1,000,000 is 1^1000000.
In conclusion, the number 1 is a unique and fundamental number in mathematics, with its own set of properties and characteristics. It serves as the base of the number system and plays a significant role in the study of divisibility, multiples, powers, and factorization.
