If a number $\text{'}x\text{'}$  divides another number $\text{'}y\text{'}$  exactly, then we say that $\text{'}x\text{'}$  is a factor of $\text{'}y\text{'}$ and is represented as $\frac{y}{x}$ .

Factors and Divisibility

Definition: If a number 'x' divides another number 'y' exactly, then we say that 'x' is a factor of 'y' and is represented as y/x.

Explanation:

• When one number x divides another number y without leaving any remainder, it means x is a factor (or divisor) of y.
• The expression y/x represents how many times x can be multiplied to give y.
• This is a fundamental concept in number theory and helps in understanding divisibility, factors, multiples, and prime factorization.

Key Points:

• Factor: A number that divides another number exactly without leaving a remainder.
• Divisibility: A number y is divisible by x if the remainder is zero when y is divided by x.
• Representation: If x is a factor of y, then y = x × k, where k is a whole number.
