What pair of numbers between 200 and 300 has a gcf of 18?
To have a gcf of 18 they must have one factor of 18 in common and no other factor, ie the second factor of the numbers must be relatively prime. The multiples of 18 between 200 and 300 are: 12 x 18 = 216 13 x 18 = 234 14 x 18 = 252 15 x 18 = 270 16 x 18 = 288 12 is relatively prime to 13 13 is relatively prime to 14, 15 & 16 14 is relatively prime to 15 15 is relatively prime to 16 (Pairs of numbers are being considered, so as 12 is relatively prime to 13, 13 is also relatively prime to 12 and thus is only listed when the numbers increase, ie under 12 and not under 13.) Thus the pairs: 216 & 234 234 & 252 234 & 270 234 & 288 252 & 270 270 & 288 all have a gcf of 18.
Find 3 numbers whose GCF is 18?
You can multiply the number 18 by different numbers that are relatively prime, for example by different prime numbers.
Are 22 and 64 relatively prime?
22 is not relatively prime
Are 20 88 and 165 relatively prime?
yes, they are relatively prime.
Wholesale price 18 Markup percent 105?
Selling price = 18 + 18 x 105% = 18 + 18 x 105/100 = 36.90
Is 18 and 105 relatively prime numbers?
No.
Is 42 and 105 relatively prime?
No, they are not relatively prime.
Are 96 and 105 relatively prime numbers?
No, they are not relatively prime.
Are 62 and 105 relatively prime?
no
Is 105 and 154 relatively prime?
No.
Is 96 and 105 relative prime?
Yes, 96 and 105 are relatively prime because they have no prime factors in common.
How many numbers less than 105 are relatively prime to 105?
Eleven numbers less than 105 are relatively prime to 105. They are 82, 83, 86, 88, 89, 92, 94, 97, 101, 103, and 104.
Are 35 and 105 relatively prime?
No. To be relatively prime, numbers have to have a GCF of 1. Numbers ending in 5 are divisible by 5.
What numbers are relatively prime with 18?
All odd numbers that can not be divided by 3 evenly would be relatively prime with 18.
Are 18 and 45 relatively prime?
No, they are not.
Are 8 and 18 relatively prime?
no
Are 25 and 18 relatively prime?
Yes, they are. 5 is the only prime factor of 25 and 5 is not a factor of 18, so they have no prime factors in common, which is what relatively prime means.
