1 and 5
Multiply 5 by the first 12 integers: 1, 2, 3, ... ,12.
Yes, all numbers greater than 1 are.
All pairs have the same same number of multiples: [countably] infinitely many.
The only integer with both those as multiples is 1.The only integer with both those as multiples is 1.The only integer with both those as multiples is 1.The only integer with both those as multiples is 1.
11, 22, 33, 44, 55 ie 1 x 11, 2 x 11 etc.
Yes, all multiples of 2 that are greater than 2 are composite numbers. In addition to 1 and the number itself, 2 is a factor of all even numbers.
This cannot be determined because the multiples of any number greater than one (1) are infinite.
The first 4 multiples of 1 are: 1, 2, 3, and 4.
-- All but one of them are greater than 8 . -- All but one of them are written with more than 1 digit. -- All are multiples of 4 . -- All are multiples of 2 . -- All are even numbers. -- All are positive, real, natural, integers.
Just calculate 11 x 1, 11 x 2, etc.
No. You can tell this by looking at the first number 1 is greater than 0
