To find the HCF you first need to break the numbers down into their prime factors. In this case we have: 30 = 2x3x5 45 = 3x3x5 The next step is to identify any common factors. In this case both numbers have 3 and 5 as prime factors. To find the HCF, multiply these together: 3x5 = 15. To get the LCM, multiply the numbers together then divide by the HCF: 30x45/15 = 90.
The GCF is 15.
The GCF is 30.

HCF(26, 45) = 1. The numbers are co-prime.
The GCF is 15.
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.
The HCF of 30 and 105 is 15.
The least common factor of any set of integers is 1.
The GCF is 15.
The GCF is 5.
