The GCF is 3.
3. 15/3 = 5. 27 / 3 = 9. 30/3=10
hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime
It is: 27 to 44 by dividing them by their hcf which is 15
The HCF is: 2
It is: 9
The GCF is 9.
3
The GCF is 3.
If you mean: 18, 27 and 36 then it is 9
