Factors of numbers are divisible by them with no remainders

It helps you not to put the wrong answer and it helps you to not write anything down.

3+7=10

Yes, you can. Using the divisibility rules, you can quickly tell that 87 is divisible by 3 (the digits add up to 15, which is divisible by 3). 3 x 29 = 87

I could write the program quickly, but I want to leave you part of the fun.Just write a loop for the numbers from 2-100 (1 is not considered a prime number). Write a second loop to test divisibility of each number, "n", with all factors lower than that number (from 2 to n-1). If such a factor exists, the number is NOT a prime number.To test for divisibility, use the remainder of a division.if (n % factor == 0)// If true, it is divisible.

Factors: Are numbers that are multiplied to make a product. You always have to write the factors in order. If you need to find the factors of a number you can use divisibility rules. (they are used to know if a number is divisible by another numberDivisibility rules: by 2 : if the number ends in an even number, 2,4,6,8....by 3: if the addition of the number is a multiple of 3by 4 : if the last two numbers are divisible by 4( zero is an exception)by 5: if the number ends in 0 or 5by 6: if the number is divisible by 2 and 3by 9: if the addition of the number is a multiple of 9by 10: if the number ends in 0.Example: the factors of 1,2,4,8,16 16 is divisible by those numbers.1x16 2x8 4x4Multiple: Is the product of a number multiplied with any other factor or factors.Multiples are endless!!!Example the first 10 multiples of 6 are: 6,12,18,24,30,36,42,48,54, 60the first 10 multiples of 2 are:2,4,6,8,10,12,14,16,18,20

Common factors are the factors that two or more numbers have in common. The common factors of 4 and 6 are 1 and 2. (This is one way to write it.) Some people write it as: 1 and 2 are the common factors of 4 and 6. Some people write it as: common factors (4,6) = 1, 2 If you writing the greatest common factor, which is the largest of the common factors, you can write it in words, as above, or as: GCF (4,6) = 2.
