No, 54 and 165 are not relatively prime.

Yes, they are relatively prime.

yes, they are relatively prime.

no

No

The GCF is 33, which means they are not relatively prime.

Yes.

Numbers 3.5 and 11. The numbers are actually prime factors of 165 (165=3*5*11).

No, they are both divisible by 3.

3 x 5 x 11 = 165

√144 < √165 < √169 12 < √165 < 13

3 * 5 * 11 = 165 Divide by prime numbers until you get a final prime number

3 x 5 x 11 = 165

They are: 3*5*11 = 165

3 x 5 x 11 = 165

3 x 5 x 11 = 165

3, 5 and 11

since they are relatively prime, the LCM is 15x11=165 Doctor Chuck

3 x 5 x 11

Prime factorization is a very difficult problem, and top mathematicians and computers have not solved it. But for small numbers, it is possible to use trial and error to find the prime factorization of the number. The first thing to note is that if a number is the product of two prime numbers, neither prime is larger than the square root of the number. So, for 165, √165 ~ 13. So, now comes the trial and error. Is it divisible by 2? No, it's not an even number. Is it divisible by 3? Let's see, do the individual numbers add up to a multiple of 3? 1+6+5=12 and 1+2=3. So, 3 is one factor. Now that we know the first factor, it's just a simple division problem to find the other factor. 165/3 = 55. But wait a minute; 55 isn't prime. It's 5*11. So the prime factors of 165 are 3, 5 and 11. This means that there are no "2" prime numbers that multiply to 165. There are 3 prime numbers that multiply to 165.

Prime factor both numbers then multiply all the numbers the number of times it appears the most. 165=3x5x11 195=3x5x13 3x5x11x13=Lcm=2145

The prime factorization of 165 is 3 x 5 x 11.

Prime factor each term then multiply all the common prime numbers together to get the GCF. 42=2x3x7 165=3x5x11 GCF=3

165 is composite

The prime factors of 165 are: 3, 5, 11
