The HCF of both numbers is 6
The HCF of 124 and 72 is 4.
The Highest Common Factor (HCF) of 18 and 30 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, we need to determine the common factors of 18 (1, 2, 3, 6, 9, 18) and 30 (1, 2, 3, 5, 6, 10, 15, 30) and identify the largest one they share, which is 6. Therefore, the HCF of 18 and 30 is 6.
HCF(30, 36, 42) = 6 LCM(30, 36, 42) = 1260
