Read slowly. You must first find the smallest number that can be divided into the number you want to factor without leaving a remainder. Whatever the result is, you divide again by a number that allows you to divide it without leaving a remainder. You continue to divide until you have broken if you divide it any further the answer will be 1. The numbers that you have used to divide are then lined up side by side and you place periods (multiplication symbols) between each one. This symbolizes that in order to get the number you have just factored you must multiply the numbers in this way.
To determine which numbers 404 is divisible by, we can test divisibility rules for common factors. 404 is divisible by 1, 2, 4, 101, and 404 itself. These numbers evenly divide into 404 without leaving a remainder.
Numbers that are not factors of 60 are those that do not divide evenly into 60 without leaving a remainder. For example, prime numbers such as 7, 11, and 13 are not factors of 60 because they cannot divide 60 evenly. Additionally, any number that is not a divisor of 60, such as 25 or 49, would also not be a factor of 60. In general, any number that does not evenly divide into 60 without leaving a remainder is not a factor of 60.
The greatest common divisor (GCD) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the GCD of 165 and 297, you can use the Euclidean algorithm. First, divide 297 by 165 to get a quotient of 1 and a remainder of 132. Then, divide 165 by 132 to get a quotient of 1 and a remainder of 33. Finally, divide 132 by 33 to get a quotient of 4 and a remainder of 0. Since the remainder is 0, the GCD of 165 and 297 is 33.
1, 2, 7 and 14 all divide into both 14 and 84, without leaving a remainder.
