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 is the divisibility the factor pairs for 80?
(80,1)(40,2)(20,4)(16,5)(10,8)
What divisibility rules can be used to find the factor pairs of 80?
Those for 1, 2, 4, 5 and 8.
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.
Are factor pairs ever repeated across pairs?
Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.
What are all the factor pairs for 75?
The prime factors of 75 are 3,5,5 as 3*5*5=75. This can be determined by testing 75 for divisibility by prime numbers starting from 2. Using the prime factorization you can determine that all the factor pairs are (3*5)*5=15*5 and 3*(5*5)=3*25
What are the factor pairs for 35?
the factor pairs are 1x35 & 5x7
What are the factor pairs 28?
The factor pairs of 28 are :28,114,27,4
How many factor pairs in 3000?
Sixteen factor pairs.
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 are the factor pairs of 0.64?
Factor pairs refer to integers, not decimals.
What are the factor pairs of 57?
The factor pairs of 57 are 3x19 and 1x57
