Explain how to find all the factor pairs of40?
From the rules of divisibility, we know that 40 is divisible by 1, 2, 4 and 5. Divide those numbers into 40 to get the rest. (40,1)(20,2)(10,4)(8,5)
How divisibility rules can help you find common factors?
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.
What are reasons of using the disivility rules?
You can always check on the divisibility of a number by dividing it into another number. But if you know the divisibility rules, you can get that information easier and faster.
How can you determine whether one number is a factor of another?
Divide the smaller into the larger. If the quotient is an integer, the smaller is a factor of the larger.
What divisibility rules determine which will divide evenly into 2 and 895?
You should learn to make your question clear to someone who doesn't know what you are doing. And why 895 of all numbers? If I guess what you want correctly, first you should factorize 895 = 5 * 179.. a number is divisible by 2 * 5 * 179 if and only if it is divisible by 10 and 179 separately, because 10 and 179 have no common factor. You should know the divisibility rules for 10 already. For 179, there isn't a simple test.
What does it means to use the divisibility rules to find factor pairs for eighty?
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.
What divisibility rules can be used to find the factor pairs of 80?
Those for 1, 2, 4, 5 and 8.
Which factor of 4587 uses divisibility rules?
Three
How can you use divisibility rules to make a factor tree for 864?
By using the divisibility rules, I can tell that 864 is divisible by 2, 3, 4, 6, 8 and 9. By dividing those numbers into 864 I can create factor pairs, any of which I can use to start the tree. 864 432,2 216,2,2 108,2,2,2 54,2,2,2,2 27,2,2,2,2,2 9,3,2,2,2,2,2 3,3,3,2,2,2,2,2
How do you know when you fount all the factor pairs of 26?
You only have to test the numbers 1 through 5. If you know the rules of divisibility, you know that 3, 4 and 5 aren't factors.
What is the greatest common factor of 91 and 49 using the divisibility rules?
It is: 7
Explain how to find all the factor pairs of40?
From the rules of divisibility, we know that 40 is divisible by 1, 2, 4 and 5. Divide those numbers into 40 to get the rest. (40,1)(20,2)(10,4)(8,5)
What divisibility rules were combined to make the divisibility rule of 36?
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
How divisibility rules can help you find common factors?

What are divisibility rules used for in real life?
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.
