The biggest factor of 108 is its own number, that is, 108. Related mathematical knowledge is introduced as follows:

I. Brief introduction of elements:

1. In primary school mathematics, two positive integers are multiplied, so both numbers are called factors of product, or divisors. It should be noted that this relationship only holds if the dividend, divisor and quotient are integers and the remainder is zero. When learning factors and multiples in primary school mathematics, the factor of 0 is not considered.

Generally speaking, the integer a is multiplied by the integer b to get the integer c. Integer a and integer b are both called factors of integer C. Conversely, the integer C is a multiple of the integer A and a multiple of the integer B. ..

Second, the relevant nature:

1. If the integer A is divided by the nonzero integer B, the quotient is an integer and the remainder is zero. We say that A is divisible by B or B is divisible by A. A prime number refers to a natural number with exactly two positive factors. Or defined as a number that cannot be divisible by other natural numbers except 1 and the integer itself.

2. The composite number has other positive factors besides 1 and itself. If A is a factor of B and A is a prime number, then A is a prime factor of B. 1 number of positive factors of nonzero natural numbers is limited, of which the smallest is 1 and the largest is itself. The multiples of nonzero natural numbers are infinite.
