The GCF is 5.
5 and 30, respectively.
The Highest Common Factor (HCF) of 165 and 150 is 15. To find the HCF, you can list out the factors of each number and identify the highest common factor. The factors of 165 are 1, 3, 5, 15, 33, 55, and 165. The factors of 150 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150. The highest common factor between the two numbers is 15.
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
HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2
It is 1 but the HCF is 5
The HCF is '10'
The GCF is 15.
hcf(5, 15) = 5 lcm(5, 15) = 15.
The GCF is 15.
The GCF is 5.
