The Highest Common Factor (HCF) of 63 and 21 is 21. To find the HCF, you can list the factors of both numbers and find the highest number that divides both evenly. In this case, the factors of 63 are 1, 3, 7, 9, 21, and 63, while the factors of 21 are 1, 3, 7, and 21. The highest number that appears in both lists is 21, making it the HCF.
The HCF of the given numbers is 1
9= 3x3 12= 2x2x2x2x3 HCF = 3
HCF is the highest common factor of two or more numbers. HCF of 9 and 15 is 3.

hcf(18, 54, 81) = 9. Using prime factorization: 18 = 2 x 3^2 54 = 2 x 3^3 81 = 3^4 hcf = 3^2 = 9
lcm(9, 12) = 36; hcf(9, 12) = 3.
The HCF is 3
