Is 40 relativley prime?
It can be. 40 is relatively prime to 41. 40 is not relatively prime to 54.
Is 34 relatively prime?
It can be. 34 is relatively prime to 35. 34 is not relatively prime to 40.
Are 30 and 40 relatively prime?
No, 30 and 40 are not relatively prime. Their greatest common factor is 10.
Are 40 and 63 relatively prime numbers?
ya they are relatively prime
Is 40 relatively prime?
One number, by itself cannot be relatively prime - or otherwise. Relative primality is a property of two (or more) numbers.
Are 40 and 21 relatively prime?
Yes.
Is 40 51 144 192 relatively prime?
No.
Is 40 relatively prime with 110?
No, they can be both divided by 10
Is 40 an 135 relatively prime?
No, because 5 divides both 40 and 135.
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.
Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement?
The numbers are not relatively prime, because they have a common factor of 2. To simplify, any pair is relatively prime, if their GCD is 1. In this case, GCD(38,40) = 2 which is not equal to 1, thus, they are not relatively prime.
Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect?
Relatively prime numbers only have 1 as a common divisor. 38 and 40 have 1 and 2.
