63 and all its multiples.
1, 3, 7, 21.
3 & 7 (and of course, 1 and 21)
Example: Here are your numbers. 9/8 7/3 1/4 1/5 first, divide 9/8 by 7/3 for dividing, you flip the reciprocal for the second fraction and multiply. then, you divide your 1/4 by 1/5 Flip the reciprocal for the second and multiply.
prime numbers that divide into 1155 = 3, 5, 7, 11
To find the mean, you add all of the numbers and divide by how many numbers you added together. 7+2+3+2+1=15. 15/5=3. The mean is 3.
1 2 3 6 7 14 21 42.
1, 2, 3, 6, 7, 14, 21, and 42
To find the average of a number, first you add all the numbers that you want to average. Then you need to divide the sum of the numbers by the number of numbers there were. So if a set of numbers is 3, 5, 7, 1, 4, 7, 8 The equation would be 3+5+7+1+4+7+8=35/7(for the 7 numbers)=5
1. you add up all of the numbers that you have. And then you divide the number of numbers you had so if i did 6,5,7 i would do 6+5+7=18 then i have three numbers so divide 18 by 3=6 and that would be my answer
They are: 3 and 7
The LCM is 84
