Not sure what "multiple combinations means.

There is only one 7-number combination and that is 1234567 or 1357642 or any one of the other permutations.

Q: How many 7 numbers combinations can you make from 1 2 3 4 5 6 7 and you can use multiple combinations but still use each number only once?

Yes there can be.* * * * *No, there cannot!There is really so such thing as a "greatest common multiple." Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.

The five that immediately come to mind (and I assume you are looking for) are: 12345 23451 34512 45123 51234 However, these are not the only combinations available as demonstrated below. Note: This just a representative sampling and is not all inclusive. 21345 23145 23415 13245 13425 13452

If the 1, 2, 3, 4 and 5 each appear in the numbers (no repeats, no eliminations-- so numbers like 11133 are not valid) then there are 120 combinations. If you can use any of the 5 any number of times up to a max of 5 times, (any possible way of making a 5 digit number using only 1, 2, 3, 4 and 5, so that 33455 for example is valid) then the number of combinations is 3125. The 3125 combinations include the 120 combinations above. This is a permutation of 5 objects, that can be thought of as an arrangement or a rearrangement of the five numbers. The number of permutations of this 5 numbers is equal to 5!. 5! = 5 x 4 x 3 x 2 x 1 = 120 ways. Or you can use the graphing calculator to compute 5!, such as: Press 5, MATH, with the right arrow go to PRB, press 4 (for !), ENTER.

There is no such number. The LEAST COMMON MULTIPLE (LCM) is the smallest number that is a multiple of both numbers (or all numbers in a set). It is used to make common denominators. The GREATEST COMMON FACTOR (GCF) is the largest number that is a factor of both numbers (or all numbers in a set). It is used to reduce fractions to simplest form.

There is really so such thing as a "greatest common multiple." Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.
