256=2^8, then the factors are 2,22,23,24,25,26,27,28
1, 639 Then by inspection of the number 639 , we note that each number is a multiple of '3' . So '3' is a factor. Also , slightly more 'tricky'. If we add the digits of 639 ; 6 + 3 + 9 = 18 1 + 8 = 9 . This means that the number has '9' is a factor. NB This only applies to factors/multiples of '9' Finally, divide 639 by 71 and/or 213 . If you have a whole number answer (No decimals), then those numbers are also factors of 639. Hence 639/71 = 9 & 329 / 213 = 3 So allthe given numbers are factors of 639.

The factors of 1,278 are: 1 2 3 6 9 18 71 142 213 426 639 1,278
That is incorrect. The common factors of 500 and 256 are 1, 2, 4.
The numbers below 500 having the most prime factors are 256 and 384 with eight prime factors each. Prime factorization is 256=2x2x2x2x2x2x2x2 and 84=2x2x2x2x2x2x2x3.
1, 3, 9, 71, 213, 639
It is: 256/500 times 100 = 51.2%
Six factors.
639 is a composite number. Its positive integer factors are: 1, 3, 9, 71, 213, 639
The factors of 256 are the numbers that can be multiplied together to equal 256. These factors include 1, 2, 4, 8, 16, 32, 64, 128, and 256. Each of these numbers can divide evenly into 256 without leaving a remainder, making them factors of 256.
The factors of 256 are: 1 2 4 8 16 32 64 128 256
The factors of 256 are: 1, 2, 4, 8, 16, 32, 64, 128, 256
Prime factors of 256=2x2x2x2x2x2x2x2 (or 28)
154 is the sum of the proper factors of 256.
256=2^8, then the factors are 2,22,23,24,25,26,27,28
