Characteristics of multiples of 2:
The mantissa is one of the five numbers 0, 2, 4, 6 and 8.
(2) both can be divisible by 2.
(3) are even numbers.
2 is a natural number, a positive integer between 1 and 3, even number.
There are many mathematical properties. If a number is divisible by 2, it is even, if it is odd.
2 is the smallest prime number (also called prime number) and the only even prime number with only 1 and 2 factors.
Extended data
According to the definition of multiple, 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.
However, 2÷2= 1, which means 2 is 1 times of 2.
However, 4÷2=2, so 2 times 4.
Multiply:
An integer can be divisible by another integer, which 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.
A number has countless multiples, that is, the set of multiples of a number is infinite. Note: you can't call a number a multiple alone, you can only say who is a multiple of who.
