For the first seven numbers:
1 / 7 gives a remainder of 1
2 / 7 gives a remainder of 2
3 / 7 gives a remainder of 3
4 / 7 gives a remainder of 4
5 / 7 gives a remainder of 5
6 / 7 gives a remainder of 6
7 / 7 gives a remainder of 0
... for a total of 21.
After this, the pattern repeats. So, you need to find the closest multiple of seven that is less than 2010, see how many "cycles" you have there, multiply the number of cycles by 21, then separate calculate the remainder for the last few numbers.
46 can be divided by these numbers without leaving a remainder: 1 2 23 and 46.
931 divided by 931 equals 1 with a remainder of 0. All multiples of 931 can be divided by 931 leaving no remainder.
1 can be divided into both numbers with no remainder
49 can be divided by these numbers without leaving a remainder: 1 7 and 49.
Any whole number can be divided by 1 without leaving a remainder.
That's the definition of a multiple.
3.6667
Any number. Can be divided by 1 without remainder.
Any multiple of that number can be.
Six.
That's the definition of a multiple.
105 can be divided evenly by 1, 3, 5, 7, 15, 21, 35, and 105. These are all the factors of 105, meaning they divide into 105 without leaving a remainder. Additionally, 105 can be divided by other numbers that are not factors, but those divisions will result in remainders.
