Is the Factor of Every Number

_____ is the factor of every number.

Answer: As we know, factors are all numbers that complete a number. It is called the coefficient of this number, leaving no remainder. A multiple of a number is the number you want when multiplied. All of these multiples can be individually named as a factor of the specified number. 

Since there is no remainder to find the factor of a given number, each number is expressed as a product of prime numbers.

For example, 1, 8, 21, 29

Factor of 1 = 1

Factor of 8 = 1, 2, 4 and 8

Factor of 29 = 1 and 29

From the data above, we can see that 1 is the largest factor in itself and the smallest factor in the other numbers. 

Therefore, 1 is the factor for each number.
