There can be only one combination with four digits. Changing their order gives permutations, NOT combinations.The following are possible combinations:1 digit: 1, 4, 6.2 digit: 11, 14, 16, 463 digit: 114, 116, 146.
There are 840 4-digit combinations without repeating any digit in the combinations.
There are 8 different combinations.There are 145 permutations that total 14.Not asked, but answered for completeness sake; there are 1296 possible permutations of four dice, making the probability of a sum of 14 being 145 in 1296 or about 0.1119.
14
Any pair of digits (not including 0), can be used to generate 14 four-digit numbers. If one of the digits is 0, only seven will start with a non-zero digit.
Four. They are 14, 21, 28, and 42.

There is no one-digit number that is equal to both 14 and 28.
1 and 11 and 21 and 31 and 42 and 12 and 22 and 32 and 43 and 13 and 23 and 33 and 44 and 14 and 24 and 34 and 416 combinations
Eight hundred and twenty-four abc c=1/2a b=1/2c So lowest is b so start with b=1 412 = 7 now make b=2 824 = 14
Oh, what a delightful little puzzle we have here! To find a four-digit number that is divisible by both 8 and 9, we can look for a number that is divisible by their least common multiple, which is 72. So, let's find a multiple of 72 that is a four-digit number, like 1008. Such a harmonious number, don't you think?
The greatest place value will be whatever non-zero digit is farthest to the left. Look at the digit immediately to the right of it. If that digit is four or less, zero it and everything to the right of it out. If that digit is five or higher, increase the greatest digit by one and zero everything to the right of it out.
