if the difference of the sum at the alternate places is divisible by 11 then it is divisible by 11
No. For instance, 101 is not divisible by 11.
8 of the numbers less than 660 are divisible by 5 and 11 but not 3. All numbers divisible by 5 and 11 are multiples of their lcm; lcm(5, 11) = 55 All numbers divisibile by 5, 11 and 3 are multiples of their lcm; lcm(5, 11, 3) = 165 659 ÷ 55 = 11 54/55 → 11 numbers less than 660 are divisible by 5 and 11 659 ÷ 165 = 3 164/165 → 3 numbers less than 660 are divisible by 5, 11 and 3 → of the 11 numbers less than 660 divisible by 5 and 11, 3 are also divisible by 3 → 11 - 3 = 8 numbers less than 660 are divisible by 5 and 11 but not 3,.
There are 6 numbers between 1 and 70 that are divisible by 11. These numbers are: 11; 22; 33; 44; 55; 66.

The list of numbers that are divisible by 11 is infinite. The first four are: 11,22,33,44 . . .
There are 6 numbers between 1 and 70 that are divisible by 11. These numbers are: 11; 22; 33; 44; 55; 66.
Yes. It equals 45. A quick rule for numbers to see if they are divisible by 3 is to add all the numbers, for example: 207 = 2 + 0 + 7 = 9 Is 9 divisible by 3...Yes! It helps reduce the large numbers, for an easier answer. The number 8649... 8 + 6 + 4 + 9 = 27 and 27 is divisible by 3, so 8649 is also divisible by 3. BUT...137: 1 + 3 + 7 = 11 11 is not divisible by 3...so, 137 is not divisible by 3.
