Unique factorization usually means that any integer can only be factored in one way using prime numbers only: 24 = 2 x 2 x 2 x 3 (unique prime factorization) If other numbers than prime numbers are allowed, factorization is not unique. 24 = 2 x 12 = 3 x 8 = 4 x 6 = -4 x -6 = etc. (non-unique factorization) If 1 is allowed, then every number has an infinity of factorizations: 5 = 1 x 5 = 1 x 1 x 5 = 1 x 1 x 1 x 5 = etc. So, limiting the allowed factors to prime numbers, makes the factorization unique. The theorem is that every integer has a unique prime factorization. So, the answer to your question could be any number showing its unique prime factorization.
Numbers are unique and so the decimal number 11 is 11 and no second number.

There are (75 x 74)/2 = (75 x 37) = 2,775 unique pairs.
A prime number is a number in the set of positive integers such that it is only divisible by 2 unique numbers: itself, and 1. For this reason the first prime number is 2, not 1.
2/1 can only be slightly simplified to 2 as there are no lower terms. 2 is a prime number and cannot be factored into smaller numbers. 1 is a unique number which also cannot be factored into smaller numbers
Because the prime numbers between 1and 50 only have exactly 2 unique factors.
1 can be seen as a unique number or a prime number depending on who you ask. 2, 3, 5 are other prime numbers in this set
The counting numbers are {1, 2, 3, ...}. The integers are the counting numbers, their opposites (-1, -2, ...) and zero. So they are {..., -2, -1, 0, 1, 2, ...}.
The Fibonacci numbers is a series of numbers that are found in nature and other things. The series goes 0,1,1,2,3,5,8,13,21 and so on. You just add the last two numbers in the series. 0+1=1, 1+1=2, 2+1=3, and so on.
The whole numbers from 1 upwards: 1, 2, 3, and so on ... Or from 0 upwards in some fields of mathematics: 0, 1, 2, 3 and so on ... No negative numbers and no fractions.
All numbers are unique so there are nu numbers which are exactly equivalent. 0.80 has the same numerical value but it also indicates a higher degree of accuracy.
