Which numbers have 3 but not 4 as a factor?
Take the multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, etc. Now, eliminate every fourth number in the sequence (the multiples of 4). The remaining numbers will be multiples of 3, but not of 4.
Are 4 and 21 relatively prime?
Yes, 4 and 21 are relatively prime. Numbers that are relatively prime only have the number 1 as a common factor. That is the case with 4 and 21.
What goes into 18 and 21 evenly?
46
What are the 4 factors 21?
1, 3, 7 and 21.
What is the greatest common factor of 21 and 77 and 84?
The GCF of 21, 77, and 84 is 7. First you have to find the lowest common factor, that is able to be divided by all the numbers. E.g. 7 *21/7=3 *77/7=11 *84/7=12 3 and 11 are prime numbers and can therefore not be any divided further. Therefore the answer is 7.
In 21 dares do you do 4 numbers or 3?

How do you get the number 21 out of the numbers 1 2 3 4?
1+2=3 3+4=7 7x3=21 (1+2)x(3+4)
Find two numbers that have a product of -21 and a sum of 4?
Seven and minus three; 7*(-3) = -21 & 7 + (-3) = 4.
What numbers can you multiply to get 21 and add to get 4?
I think one or both of those have to be negative. -3 + 7 = 4 -3 x 7 = -21 3 + -7 = -4 3 x -7 = -21 7 x 3 = 21 7 - 3 = 4 It also works if you subtract.
What is the average of 4 8 and 9?
4+8+9= 21 divide 21 by 3 (you have three numbers) = 7
What is 21 dares?
21 Dares is a mathmetical concept game. I'm not exactly sure how to play but it has somthing to do with cards! ---------------------------------------- I would like to add something to that. The version of 21 dares that I play doesn't need cards. You need at least 2 people, and you go around in a circle counting upwards in threes until someone says the number '21'. So the person who starts off says either "1" or "1, 2" or "1, 2, 3". You can say a minimum of one number and a maximum of three numbers. And then the second person carries on from where the last person left off, again with a max of three and a min of 1. So, for example, if the first person had said, "1, 2" the second person could say, "3" or "3, 4" or "3, 4, 5". And so on. The person who says "21" must do a dare of any other player's choice.

How do you find the median of numbers?
Put the numbers in order. Add them all together then divide by the amount of numbers in the line. For example: 1 2 3 4 5 6 = 21 21 divide by 6 is 3 r 3 so your answer is 3.3
