No, they are both divisible by 3.
no
No
The GCF is 33, which means they are not relatively prime.
No, 54 and 165 are not relatively prime.
Yes, they are relatively prime.
yes, they are relatively prime.
No, 144 and 165 are not relatively prime. For them to be relatively prime, the number 1 could be their only common factor, but they also have 3 as a common factor.
no 99 is divisible by 1 and 9
Yes.
1, 3, 9, 11, 33, 99 3 and 11 are prime. 1, 3, 5, 11, 15, 33, 55, 165 3, 5 and 11 are prime.
3 x 3 x 11 = 99 3 x 5 x 11 = 165
Since 167 is a prime, any number smaller that 167 will be relatively prime. So, the largest number less than 100, that is 99, is relatively prime.
