1 has 1 factor.
36
Every number has 1 as a factor. 6 and 9 are not factors of 1 as they are both greater than 1 and all factors of a number are less than or equal to the number. The least whole number with 6 and 9 as factors is the lowest common multiple of 6 and 9 lcm(6, 9) = 18 6 = 2 × 3 9 = 3² → Lcm = 2 × 3² = 18
196, 169, 144
product of a fraction less than 1 and a whole number greater than or less than the whole Number
The closest whole number to 3/8 would be 1. It is less than the first whole number.
That would be 1. The only factor of 1 is 1. All other whole numbers have at least two factors. Prime numbers have exactly two factors, while composite numbers have more than two factors.
There are 12 numbers less than 150 which have an odd number of factors: 1,4,9,16,25,36,49,64,81,100,121,144.

1 has one factor.
the number 90 has the most factors under 100
The three greatest whole numbers less than 200 that each have an odd number of factors are 144, 169 and 196.
A whole number has an odd number of unique factors if and only if it is a perfect square. The perfect squares less than 10 are 0, 1, 4, and 9. Therefore, there are four whole numbers less than 10 that have an odd number of unique factors.
It is 97 which has only two factors because it is a prime number
360, 420 and 480 each have 24 factors.
The numbers 60, 72, 84, 90, and 96 each have 12 factors.
