Since 4 is a factor of 120, it is automatically the GCF.
The GCF of 16 and 100 is 4.
It is: 4
The greatest common factor (GCF) of 100, 120, and 144 is the largest number that divides evenly into all three numbers. To find the GCF, we first need to find the prime factors of each number: 100 = 2^2 * 5^2, 120 = 2^3 * 3 * 5, and 144 = 2^4 * 3^2. The GCF is the product of the common prime factors raised to the smallest power they appear in all three numbers, which is 2^2 = 4. Therefore, the GCF of 100, 120, and 144 is 4.
The factors of 120 are:1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120The factors of 210 are:1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210The common factors are:1, 2, 3, 5, 6, 10, 15, 30The Greatest Common Factor (GCF) is:30
