3 is the hcf
3 12 = 2^2 x 3 21 = 3 x 7 30 = 2 x 3 x 5 hcf = 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 6.
The HCF of the given numbers is 1
By dividing the numerator and denominator by HCF which is 6: 12/30 = 2/5 reduced
Factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 41, and 84Factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60The HCF of 84 and 60 is 12
