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.
A number with more than two factors is called a composite number. Composite numbers can be divided evenly by numbers other than just 1 and themselves. For example, the number 4 has factors of 1, 2, and 4, making it composite. In contrast, numbers with exactly two factors (1 and themselves) are called prime numbers.
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.
How about: 8 and 16
They are: 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.
