To find the Highest Common Factor (HCF) of 45, 75, and 125, we need to first find the prime factors of each number. The prime factors of 45 are 3 x 3 x 5, the prime factors of 75 are 3 x 5 x 5, and the prime factors of 125 are 5 x 5 x 5. To find the HCF, we look for the common prime factors among all three numbers, which are 5. Therefore, the HCF of 45, 75, and 125 is 5.
The greatest common factor (usually abbreviated GCF) of 15, 35, and 20, is 5.
