You need at least two numbers to find a GCF. If that's 4 and 5, the GCF of any two consecutive numbers is 1.
The HCF is 1.
The GCF is 1.
The GCF is 15.
HCF(26, 45) = 1. The numbers are co-prime.
The Highest Common Factor (HCF) of 45 and 40 is 5. To find the HCF, you need to determine the largest number that divides both 45 and 40 without leaving a remainder. The factors of 45 are 1, 3, 5, 9, 15, and 45, while the factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The largest number that appears in both lists is 5, making it the HCF of 45 and 40.
The GCF is 5.
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.
