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
