2 because it only has two factors, 1 and 2. I hope this helped! :D

They are 1, 2, 7 and 14.

'''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.'''

12 (factors: 1, 2, 3, 4, 6, 12) and 18 (factors: 1, 2, 3, 6, 9, 18)

16 = 2 x 2 x 2 x 2

composite numbers less than 20 which have more than 5 factors = 12 & 18 composite numbers less than 20: 4, 6, 8, 9, 10, 12, 14, 16, 18Factors of:4 = 1, 2, 46 = 1, 2, 3, 68 = 1, 2, 4, 89 = 1, 3, 910 = 1, 2, 5, 1012 = 1, 2, 3, 4, 6, 1214 = 1, 2, 7, 1416 = 1, 2, 4, 1618 = 1, 2, 3, 6, 9, 18thus 12 & 18 have more than 5 factors.

18: 1-18, 2-9, 3-6.

No, 2 Kg (Kilograms) is greater than 20g (grams).

less than

If you're allowed to repeat factors, 2 x 2 x 2 x 2 = 16. If not, no number less than 100 has more than 3 distinct prime factors.

20 grams is less than 2kg. 2kg is 2000 grams.

If there are three factors, then one of them being less than 1 does not imply anything about the product of all three and either of the other two factors. For example, 2 = 0.5*1*4 where the first factor is less than 1. The product 2 is less than one of the other factors but bigger than the last.

The only common factors of 38 and 90 are 1 and 2, so it is not possible for a common factor of 38 and 90 to be greater than 2, much less 20.

All of the numbers less than six can be factors, and all integers have a least one factor that is less than six. Here's a set of factors less than 6: (1, 2, 3, 4, 5)

All numbers have factors. For example, the number 300 has the factors 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300. Some of those factors are greater than 100, some are less than 100.

The smallest prime numbers, after 2, are 3 and 5. 3 x 5 = 15.

The numbers for which the sum of its proper factors is 1 less than the number is the powers of 2; less than 50 these are: 2, 4, 8, 16 & 32.
