the gcf of 9 and another number is 1 the LCM is 45. what is the number?

Question

the gcf of 9 and another number is 1 the LCM is 45. what is the number?

Answer 1

HCF(or gcd) OF a no.*LCM of a no.=product of 2 nos.

let the other no. be x

therefore

9*x=45*1

x=45/9=5

x=5

therefore other no(=x)=5 is the solution

Answer 2

5

Answer 3

5.

9 and 5 only share 1 as a number they can be divided by, hence gcf = 1.

least common multiple, well, 9*5 = 45 so it seems to work anyway.

Answer 4

5. Common Sense.

Answer 5

GCD(a, b)*LCM(a, b)=a*b

So 1*45=9*b -> trivial.
