There are twelve instances where the integers from 1 to 200 contain the digit 1 at least twice:-11,101,110,111,121,131,141,151,161,171,181,191.

in this numerals 0 to 99 which is least repeat digit

Positive integers are greater than negative integers. For positive integers: * The integer with more digits is larger. * If two integers have the same length, compare the first digit. If the first digit is the same, compare the second digit, then the third, etc., until you find a difference. In each case, the integer with the larger digit (at the first position where you find a difference) is the larger one.

The least common factor of any set of positive integers is 1.

Assuming the question is about positive integers and there are no leading 0s, the answer is NEVER.

5 digit telephone numbers having at least one of their digits repeated is = total possible 5 digit telephone numbers - 5 digit telephone numbers without any digit being repeated. =(10*10*10*10*10)-(10*9*8*7*6) =100000-30240 =69760

Zero. It appears only 10 times, all the others 20 times.

1111, unless you allow negative number. In that case, the answer is -9999.

There is only one number and that is 123456.

First, separate the negative and positive integers (put them into two separate groups). If there is a zero, you can put it in its own group - or put it into the same group with the positive integers. Negative integers come first, then zero, then positive integers.For positive integers:An integer with less digits comes before an integer with more digits.For integers with the same number of digits, look at the first digit. The integer with the smaller digit in this position comes first.If the first digit is the same, look at the second digit. If those are equal, look at the third digit, etc.For negative integers, it is the other way round - for example, an integer with MORE digits comes first.

At least one of the integers is negative.

Yes, at least for integers: You see how often you can subtract a quantity. But I guess it is more useful to think of division as the inverse of multiplication.

Zero.
