11
It is 3 or 11
No they are not. They have more than the number 1 as a common factor. They also have the number 3 as a common factor.
3 x 11 = 33
3 x 3 x 3 also known as 33
43 is a prime 33 is composite
eleven
11 and 33
99 is not a prime because it can be divisible by 3 and 33
Three is 33's lowest prime factor.
Because 33 isn't prime. It is divisible by 3 and 11.
It is 3 or 11
Yes, 3 is a prime factor of 33.
Answer: 33 Prime factors from 11 is 11, and prime factor from 33 is 3 and 11. Then you multiply each prime factor the greatest number of times it appears in either number. There for 11 appears once in each so 11 (1 time) times 3 which only appears once.
No they are not. They have more than the number 1 as a common factor. They also have the number 3 as a common factor.
33 is not a factor of 72.
Divide the number by it's lowest prime factor possible continuosly until you get a one. The numbers will then be the prime factors. For example: Take the number 66. 2 is the smallest prime number and it is a factor of 64. So 66/2 = 33. 33 is not divisible by 2 so we take the next lowest prime factor: 33/3 = 11. 11 is divisible by nothing but itself and so 11 is the next lowest prime factor (remember we always need the answer to remain an integer): 11/11 = 1. Therefore 66 = 2 x 3 x 11.
If there are only two digits and only two proper factors, the answer could be either 33 or 51. Three digit numbers include 123, 213 and 321
