The GCF is 5.
5 and 30, respectively.
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 1 but the HCF is 5
The HCF is '10'
The GCF is 15.
hcf(5, 15) = 5 lcm(5, 15) = 15.
Alright, buckle up, buttercup. The Highest Common Factor (HCF) of 10, 15, and 6 is 1. Why? Because the only number that can divide all three numbers without leaving a remainder is good ol' number 1. So, there you have it, the HCF is 1.
The GCF is 15.
The GCF is 5.
The GCF is 2.
The GCF is 10.
