To find the highest/greatest common factor. you must first identify the factors for each number.
For 120, its factors are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.
For 36, its factors are 1, 2, 3, 4, 9, 12, 18, and 36.
12 is the highest (or greatest) factor they have in common, so the HCF for 120 and 36 is 12.
12
The highest common factor (HCF) of 36, 40, and 120 is the largest positive integer that divides all three numbers without leaving a remainder. To find the HCF, you can first determine the prime factors of each number: 36 = 2^2 * 3^2, 40 = 2^3 * 5, and 120 = 2^3 * 3 * 5. Then, identify the common prime factors among the three numbers and take the smallest power of each common factor to calculate the HCF. In this case, the HCF of 36, 40, and 120 is 8 (2^3).
The GCF is 4.
The GCF is 9.
The GCF is 18.
The GCF is 12.
The GCF is 4.
It is 36
