The GCF is 3.
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
The GCF is 3. The LCM is 120.
Oh, dude, the highest common factor (HCF) of 12 and 15 is 3. It's like the biggest number that can divide both 12 and 15 without leaving a remainder. So, if you were wondering, now you know. Cool, right?
The HCF of 12 and 60 is 12
The GCF is 12.
The GCF is 2.
The HCF of 40 & 12 is... 4
The GCF is 15.
hcf(5, 15) = 5 lcm(5, 15) = 15.
