The number that 30 is ten less than is 40. Half that is 20. So the question becomes "what number is as much more than 10 is less than 20". This is gobbledygook, but if I rephrase to say "what number is as much more than 10 than 10 is less than 20", then since10 is less than 20 by 10, I guess 20.
The factors of 20 are: 1,2,4,5,10,20 So; 4 and 10 are the even factors of 20 which are greater than 3.

It is 19 which is a prime number
"12" has 6 factors.
12 and 18 each have six factors.

Well, darling, the number you're looking for is 15. It's less than 20, odd, and can be broken down into the prime factors 3 and 5. So, there you have it, a prime factor party with the number 15 strutting its stuff.
Your Mama! I mean 21.
'''They called composite numbers.''' '''Composite numbers are when they have more than two factors.''' '''A prime number is when it only has 2 factors no more or less.''' '''EX : 20''' '''Factors Of 20 : 1, 20, 2, 10, 4, 5.'''
They are 1, 2, 7 and 14.
91119 cannot be a factor of 20. So the question is nonsense.
Four of them.
Any number that has factors smaller than itself (other than 1) is a composite number.Any number that has factors smaller than itself (other than 1) is a composite number.Any number that has factors smaller than itself (other than 1) is a composite number.Any number that has factors smaller than itself (other than 1) is a composite number.
4 and 9. Factors of numbers come in pairs which means that every number ought to have an even number of factors. To have an odd number of factors, one factor pair must be a repeated number which means that only square numbers have an odd number of factors. The square numbers less than 20 are 1, 4, 9 & 16 and of these 4 & 9 have 3 factors: 4: 1, 2 & 4 9: 1, 3 & 9
