20
It is 20.
10
A whole number greater than 1 that has 3 or more factors is 10.
1, 2, 3, 4, 5, 6, 7, 10
1, 2, 3, 4, 5, 6, 7, 9, 10
No 81 is (9 x 9) 100 is (10 x 10) 88 is not - at least not of a whole number Square root is 9.3808315 etc
48 is the lowest of all whole numbers having 10 factors.

10
A whole number greater than 1 that has 3 or more factors is 10.
The whole-number factors of -10 are: +1, -1, +2, -2, +5, -5, +10, and -10.
1, 2, 3, 4, 5, 6, 7, 10
10/99 = 0.1010... (repeating)
1 and 20, 2 and 10, 4 and 5 are all of the pairs of factors of 20.
They are: 1, 2, 4, 5, 10 and 20
1, 2, 3, 5, 6, 10, 15, 30
48 has ten factors.
Divide the number 50 by successive prime numbers... 50/1= 50 (factors here are 1 and 50) 50/2=25 (factors here are 2 and 25) 50/3=not a whole number 50/4=not a whole number 50/5=10 (factors here are 5 and 10) Can't do it anymore. Therefore 1,50,2,25,5 and 10 are the factors of 50
