To find the least common multiple (LCM) of two numbers, you can use the following formula:
LCM(a, b) = (a * b) / GCD(a, b)
Where:
a = first number (6 in this case)
b = second number (8 in this case)
GCD = Greatest Common Divisor
Now, let's find the Greatest Common Divisor (GCD) of 6 and 8. The GCD of 6 and 8 is 2.
Plugging this into the formula:
LCM(6, 8) = (6 * 8) / 2
LCM(6, 8) = 48 / 2
LCM(6, 8) = 24
Therefore, the least common multiple (LCM) of 6 and 8 is 24.
LCM(a, b) = (a * b) / GCD(a, b)
Where:
a = first number (6 in this case)
b = second number (8 in this case)
GCD = Greatest Common Divisor
Now, let's find the Greatest Common Divisor (GCD) of 6 and 8. The GCD of 6 and 8 is 2.
Plugging this into the formula:
LCM(6, 8) = (6 * 8) / 2
LCM(6, 8) = 48 / 2
LCM(6, 8) = 24
Therefore, the least common multiple (LCM) of 6 and 8 is 24.

The correct term to use in this context is "LCM" which stands for Least Common Multiple, not LCF.
To find the LCM of two numbers, 5 and 15 in this case, you can follow these steps:
1. List the multiples of both numbers:
- Multiples of 5: 5, 10, 15, 20, 25, 30, ...
- Multiples of 15: 15, 30, 45, 60, ...
2. Identify the least common multiple, which is the smallest number that is a multiple of both 5 and 15:
- The least common multiple of 5 and 15 is 15.
Therefore, the LCM of 5 and 15 is 15.

The greatest common factor (GCF) is the largest number that divides evenly into two or more numbers.
To find the Greatest Common Factor (GCF) of 7 and 4, you can calculate the common factors:
Factors of 7 are 1, 7
Factors of 4 are 1, 2, 4
The common factors of 7 and 4 are 1, which means the Greatest Common Factor (GCF) of 7 and 4 is 1.
Therefore, none of the given numbers (14, 28, 32, 56) are the Greatest Common Factor of 7 and 4.
