The factors of 16 are 1, 2, 4, 8, and 16.
Oh, dude, the smallest number that factors into 3, 4, and 5 is 60. It's like the math stars aligned to give us this magical number. So, if you ever need a number that can be divided by 3, 4, and 5, look no further than good ol' 60.
The number 10 can be the product of 2 and 5, 1 and 10. This means that 10 has 4 factors. :]
60
1, 2, 4, 5, 8, 10, 20, 40. Technically, that's correct, but proper factors are the factors of a number EXCEPT the number itself. So, the PROPER FACTORS of 40 would be 1, 2, 4, 5, 8, 10, and 20.

The factors of 4 are 1, 2, and 4. The only prime factor of 4 is 2. The factors of 20 are 1, 2, 4, 5, 10, and 20. The prime factors of 20 are 2x2x5.
1 and 4
9000 60
Its...........60!

The factors of 16 are 1, 2, 4, 8, and 16.
Factors are numbers you can multiply together to get another number. 16: 1, 2, 4, 8, 16 16 has 5 factors.
The number 40 is a multiple of both 4 and 5.
How about 60
120
No. A good example of that is with 4. In this case 2+2 =4 and 2*2=4. Additionally, when the factors are the number itself and 1, the sum is greater than the number. For example 1*5 = 5 while 1+5 = 6.
