It is: 7
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
The answer will depend on the divisibility rules list.
Factors are divisors. If you know the divisibility rules, you know that 80 is divisible by 1, 2, 4, 5 and 8. If you divide 80 by those numbers, you find the other half of the factor pairs.
Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.
You use divisibility rules t determine whether a particular number is (or is not) a factor of another number. If it is a factor, you can reduce the numbers involved to smaller numbers.You might want to find factors to simplify fractions or to add or subtract factions.
fractions help you write out divisibility rules because divisibility rules help with fractions . Glad I would help good bye
Those for 1, 2, 4, 5 and 8.
The divisibility rules for a prime number is if it is ONLY divisible by 1, and itself.
The greatest common factor of 216 and 855 is 9.
