> 1, 3, 5, 7, 11, 13, and 17 1 is not a prime number, but 2 and 19 are. The correct answer is 2, 3, 5, 7, 11, 13, 17, and 19.
Here are some counting numbers that have two different factors: 2 has 1 and 2 3 has 1 and 3 5 has 1 and 5 7 has 1 and 7 11 has 1 and 11 13 has 1 and 13 17 has 1 and 17 19 has 1 and 19
prime numbers
How many subsets are there in 2 3 5 7 11 13 17 19 23?
1, 1, 2, 3, 5, 8, 13, 21... is the Fibonacci SeriesIt could as well be a series of prime numbers :1, 2, 3, 5, 7, 11, 13, 17, 19, etc.
They are: 2 3 5 7 11 13 17 19 and 23
If: 11x+13y = 17 Then: 11/17x +13/17y = 1 by dividing all terms by 17 So: 11/17*17/22+13/17*17/26 = 1 because 1/2+1/2 = 1 Therefore: x = 17/22 and y = 17/26 Check: 11(17/22) + 13(17/26) = 17 Check: 11(17/22) times 13(17/26) = 72.25
> 1, 3, 5, 7, 11, 13, and 17 1 is not a prime number, but 2 and 19 are. The correct answer is 2, 3, 5, 7, 11, 13, 17, and 19.
The prime numbers from 1 to 17 are 2, 3, 5, 7, 11, 13, and 17.
The prime numbers between 1 and 20 are: 2 3 5 7 11 13 17 19.
7 x 11 x 13 x 17 = ??? Well... 1) 7 x 11 = 77 2) 77 x 13 = 1001 3) 1001 x 17 = 17017!
Actually the next number in the sequence is 17 A 19 , 23 , 29 , 31 ,.......... Prim number
The factors of a number are the integers that can be multiplied together to get that number. The factors of the numbers you listed are as follows: 10: 1, 2, 5, 10 11: 1, 11 12: 1, 2, 3, 4, 6, 12 13: 1, 13 14: 1, 2, 7, 14 15: 1, 3, 5, 15 16: 1, 2, 4, 8, 16 17: 1, 17 18: 1, 2, 3, 6, 9, 18 19: 1, 19 20: 1, 2, 4, 5, 10, 20
2, 3, 5, 7, 11, 13, 17, 19, 23, and 29
Here are some counting numbers that have two different factors: 2 has 1 and 2 3 has 1 and 3 5 has 1 and 5 7 has 1 and 7 11 has 1 and 11 13 has 1 and 13 17 has 1 and 17 19 has 1 and 19
