4 * 2 * 2 = 16
4 + 4 +4 + 4 = 16
1 + 4 + 3 + 2 + 2 + 4 = 16
The word factor means you take a number [in this case it is 2] and you multiply it by another number to reach your desired numbers [in this case your desired numbers are 1, 2, 4, 8 and 16] So ask yourself 2 times what numbers equals 1 or 2 or 4 or 8 or 16 2x 0.5 = 1 2x 1 = 2 2x 2 = 4 2x 4 = 8 2x 8 = 16 Because a number can be multiplied by 2 and get the numbers you said then this 2 can be called a factor of these numbers.
-17 + 1 -18 + 2 Ect. -16 + -1 -17 + -2 Ect.
1, 2, 4, 8, 16, 32.
Numbers having only 2 factors are prime numbers. Their only factors are 1 and themselves. Prime numbers. The only two factors should be 1 and itself.
32, 16, 8, 4, 2 and 1
(1+3+4) * 2 = 16
3-1=2 then 2x2x4=16.
3-1=2 2x2=4 4x4=16 or 3-1=2 2*4=8 8*2=16
only using the numbers once
Only one - 16
2, 4, 8, 16, 32, 64
2, 4, 8, 16, 32, 64
16 has only one prime factor, and that is 2.
The only prime factor of 16 is 2.
No. That is impossible. A prime number is defined as a number that factors only to itself and the number one. A prime number MUST only be "divisible" by 1 and itself to get an integer number. For example, 7 only has 2 factors - 1 and 7. Square numbers are divisible by a number other than 1 and itself. For example, 16 has the factors 1, 2, 4, 8, and 16. 4 squared = 16
16 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1, 2, and 0. 1, 2, and 0 have a different name.
1, 2, 4, 8, 16, 32, 64 2 is the only prime factor.
