Greatest common factor of 10 and 20?
20 - 1,2,4,5,10,20 You can not have a GCF of just one number. But written are the factors of 20.
What number has 4 factors?
No, because 4 is not a factor of 14, for example.The rule for finding if a number is a multiple of 4 is: If the last 2 digits of the number are a multiple of 4, then the number is a multiple of 4.Example: here are some multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100so if the last 2 digits of the number are 04, 08, 16, ...., 96, or 00, then the number is a multiple of 4 (or you can say that 4 is a factor)234535721117575672 has 4 as a factor, because 72 are the last 2 digits.Rather than memorize all multiples of 4 to 100, just remember this:if the 'ones' digit is a 0, 4, or 8, then the 'tens' digit must be even (zero being even): example, 20, 48, 64if the 'ones' digit is a 2 or 6, then the 'tens' digit must be odd.example 16, 52, 36No. 4 and 24 have a factor of 4, but 14 and 34 do not.
What is the greatest factor of 12 and 20?
The greatest common factor of 12 and 20 is 4
What is the highest factor of 20 and 50?
The highest factor of any number is the number itself. The GCF of 20 and 50 is 10.
How do you write out a factor pair?
Factor pairs are any two numbers being multiplied to give you a certain number. Examples for 20: 1x20, 20x1, 2x10, 10x2, 4x5, and 5x4 are all factor pairs for 20.

10, 20, 25, 50

A two digit number divisible by 10?
20.
What is a two digit number which has the difference of the 2 digits equal to your largest single digit?
21 and 20
What is the three digit number that is greater than 10 and less than 20 whose tens digit is an odd number?
There cannot be a proper three digit number between 10 and 20. It must be a two digit number. If you consider a 2-digit number between 10 and 20, then its tens digit MUST be 1 and so MUST be odd. So most of this question is either wrong or irrelevant. Are you sure you have not cut and pasted bits from two questions?
If you add a two digit number to a two digit number do you get a four digit number?
No. When adding the smallest 2 digit number (= 10) to the smallest 2 digit number (again, 10) the result is a 2 digit number (10 + 10 = 20). When adding the largest 2 digit number (= 99) to the largest 2 digit number (again, 99) the result is a 3 digit number (99 + 99 = 198). As you can see, you'll either get a 2 or 3 digit number, but never a 4 digit number.
What is the probability of guessing a two digit number less than thirty?
1/20 = 5%
Which two-digit number less than 20 is multiple of both 4 and 6?

What is the common factor for the number 20?
