What are the characteristics of multiples of 2 and 5?
Characteristics of multiples of 2: each bit is a number of 0, 2, 4, 6 and 8.

Characteristics of multiples of 5: each bit is an integer of 0 or 5.

Characteristics of multiples:

1, an integer can be divisible by another integer, and this integer is a multiple of another integer. For example, 15 can be divisible by 3 or 5, so 15 is a multiple of 3 and 5.

2. The quotient obtained by dividing one number by another. For example, a÷b=c, that is, A is a multiple of B, for example, A÷B=C, it can be said that A is C times that of B.

3. A number has countless multiples, that is to say, the set of multiples of a number is an infinite set. Note: you can't call a number a multiple alone, you can only say who is a multiple of who.

Multiple solutions

(1) The quotient obtained by dividing one number by another. For example, a÷b=c, that is, A is a multiple of B, for example, A÷B=C, it can be said that A is C times that of B.

(2) According to the definition of multiple, give an example to illustrate the solution of multiple: for example, find the multiple of 3. 3 times 1, 2, 3, 4, 5 and so on. The formulas are: 3× 1=3, 3×2=6, 3×3=9, 3×4= 12, 3×5= 15 and so on.

(3) It can be concluded that 3, 6, 9, 12 and 15 are all multiples of 3.

(4) One of a number is the number multiplied by 1, and the result is itself.
