What are the divisibility rules from 1-25?

What divisibility rules can be used to find the factor pairs of 80?
Those for 1, 2, 4, 5 and 8.
What divisibility rules were combined to make the divisibility rule of 36?
You have to use the rules of 4 and 9 Using the rules of 2 and 18 won't work because the smallest common multiple of 2 and 18 is 18 not 36. 3 and 12 won't work either because the smallest common multiple of 3 and 12 is 12 not 36. However 4 and 9 does work because their biggest common divisor is 1 so multiplying them works. The biggest common divisor of 2 and 18 is 2 and the biggest common divisor of 3 and 12 is 3
What are the divisibility rules to determine if 634 is divisible by 2?
Any even number is divisible by 2.

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 10 and 20 factors of 20?
Divide by two and five. 1, 2, 4, 5, 10, 20
What is the divisibility rule for 2 squared 1?
2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.
Why does divisibility rule for 2?
The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.
Is 350 composite or prime?
350 is a composite number. it can be divisible by 10, 35, 5, 2 etc. You will find it easier to tell between prime and composite if you know the divisibility rules. one simple one is that if a number ends with zero it is divisible by 10...there are a lot of other divisibility rules.
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 are the divisibility rules to determine if 634 is divisible by 2?
Any even number is divisible by 2.
What are the divisibility rules for 2 5 and 10?
For 2 it's any even number.For 5 it's if the number ends in 5 or 0.For 10 it's if the number ends with a zero. That's basically it.
