All multiples of the lowest common multiple of {2, 4, 8} have {2, 4, 8} as factors.
lcm(2, 4, 8) = 8→ all multiples of 8 have {2, 4, 8} as factors, namely:
8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136, 144, 152, 160, 168, 176, 184, 192, 200, 208, 216, 224, 232, 240, 248, 256, 264, 272, 280, 288, 296, 304, 312, 320, 328, 336, 344, 352, 360, 368, 376, 384, 392, 400, 408, 416, 424, 432, 440, 448, 456, 464, 472, 480, 488, 496, 504, 512, 520, 528, 536, 544, 552, 560, 568, 576, 584, 592, 600, 608, 616, 624, 632, 640, 648, 656, 664, 672, 680, 688, 696, 704, 712, 720, 728, 736, 744, 752, 760, 768, 776, 784, 792, 800, ...
take your pick of two of them.
Factors. example: 2 x 2 = 4 there, 2 and 2 are the 2 numbers you multiply, factors are the numbers you multiply together. It can be more that 2 factors.
2 and 2. Prime factors needn't be distinct. Powers of the primes have only this prime as factor and 4 is a power of 2.
Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.
There are square numbers (numbers which are a square of an integer), such as 4. It's factors, listed are 1, 2, and 4. All square numbers have an odd number of factors. Then there's 1, which has only 1 factor: 1. All other numbers have an even number of factors. Prime numbers will have only 2 factors (2 is even).
The two factors in 24 are many possibilities6*4, 8*3 2*12
What two numbers have the factors 2 4 and 8
All composite numbers have more than two factors. The smallest such number is 4, which is equal to 2 x 2. 4 has three factors: 1, 2, and 4.
4 (factors 1, 2 and 4) and 9 (factors 1, 3 and 9) are two examples.
They are: 8 and 16
How about: 8 and 16
They can be: 16 and 24
If the two prime numbers are different: You get the two prime numbers, plus 1, plus the product. For example, if you multiply 2 x 3 = 6, the factors of 6 are 2, 3, 1, and 6. If the two prime numbers are the same: You get the prime number, 1, and the product. For example 2 x 2 = 4. The factors of 4 are 2, 1, 4.
Factors. example: 2 x 2 = 4 there, 2 and 2 are the 2 numbers you multiply, factors are the numbers you multiply together. It can be more that 2 factors.
Factors don't have numbers. Numbers have factors. Numbers that have the factors 2, 4 and 8 are 8 and all of its multiples.
2 and 2. Prime factors needn't be distinct. Powers of the primes have only this prime as factor and 4 is a power of 2.
Numbers that have 2 factors are prime numbers; Numbers that have 4 factors are either: * the cube of a prime; or * the product of two different primes; Numbers that have 8 factors are either: * a prime to the power 7; * the product of a prime cubed and different prime; * the product of three different primes.
