What is a divisibility rule for 5?
If the rules for 2 and 3 work, the number is divisibale by 5.
Can you tell if whether 432 is divisible by 2 3 4 5 6 9 10?
Yes, you can tell using the divisibility rules. The answers are yes for all but 5 and 10.
What are the divisibility rules from 1-25?
26
What divisibility rules can be used to find the factor pairs of 80?
Those for 1, 2, 4, 5 and 8.
What is 85743 for divisibility by 2 3 5 9 or 10?
It is divisible by 3 and 9 but not the others.
What is a divisibility rule for 5?
If the rules for 2 and 3 work, the number is divisibale by 5.
What numbers 2 3 5 9 divides into 123456789 evenly using divisibility rules?
3 and 9. And they divide into 123456789 whether or not you use divisibility rules!

Is 85743 divisibility by 2 3 5 9 or 10?
No.
Who invented the divisibility rules?
The divisibility rules were not invented by a single individual, but rather developed over time by mathematicians through observation and exploration of number patterns. The rules for divisibility by 2, 3, 5, and 10 can be traced back to ancient civilizations such as the Egyptians and Greeks. The more complex rules for divisibility by numbers like 7, 11, and 13 were further refined by mathematicians in the Middle Ages and beyond. These rules are now fundamental concepts in elementary number theory.
What divisibility rules can be used to find the factor pairs of 80?
Those for 1, 2, 4, 5 and 8.
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.
Is 10 and 20 factors of 20?
Divide by two and five. 1, 2, 4, 5, 10, 20
What is 85743 for divisibility by 2 3 5 9 or 10?
It is divisible by 3 and 9 but not the others.
What is divisibility rules for 15?
If a number is divisible by 3 and 5, it is divisible by 15.
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.
