which of these numbers are common multiples of 6 and 8? Choose ALL that apply.
6. 8. 12. 16. 18. 24 .30. 32. 36. 40. 42. 48. 54. 56.
The common multiples of 6 and 8 are numbers that are divisible by both 6 and 8.
The common multiples of 6 and 8 are:
24
48
Therefore, the correct numbers from the list that are common multiples of 6 and 8 are 24 and 48.
what is the least common multiples LCF of 6 and 8
The LCM of 6 and 8 is ?.
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.
what is the LCF of 5 and 15
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.
What is the LCF of 7 and 4?
14. 28. 32. 56.
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.
