can someone explain to me how to solve for the following:
Directions:Find the GCF of 6,18, and 30
well to get the answer you need to find the biggest comon factor that all of the numbers can evenly go into. like with 3, 6, 9 you would take 9 and write/type out several factors that 9 goes into, like, 18, 27, 36, 45, 54, 63, 72, 81 and then do the same thing with the other numbers until you find a number that all three numbers would go into evenly.
I don't know help me
To find the greatest common factor (GCF) of 6, 18, and 30, you can follow these steps:
1. Start by listing the prime factors of each number:
- For 6: 6 = 2 * 3
- For 18: 18 = 2 * 3^2
- For 30: 30 = 2 * 3 * 5
2. Identify the common prime factors among the numbers. In this case, the only common prime factor is 2 and 3.
3. Take the lowest exponent for each prime factor that appears in the list of prime factors:
- The lowest exponent for 2 is 1.
- The lowest exponent for 3 is also 1.
4. Multiply the common prime factors with their lowest exponents together:
GCF(6, 18, 30) = 2^1 * 3^1 = 2 * 3 = 6
Therefore, the greatest common factor of 6, 18, and 30 is 6.
