https://sciencetrends.com/the-factors-of-36/

So with our original question, the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18 , and 36 because 1 × 36 = 36, 2 × 18 = 36, 3 × 12 = 36, 4 × 9 = 36, and 6 × 6 = 36. Similarly, the factors of 16 are 1, 2, 4, 8, and 16; and the factors of 21 are 1, 3, 7, and 21. Some numbers, like 23, are unique in that they only have 2 factors, 1 and themselves.
