what is the LCM of 8 12 and 5
plzzzz help me its do tommra and i cant figure it out
One way to find the LCM is to find the multiples of the largest number. Then divide them by the other two numbers. Remember that a multiple of 5 must end in either 0 or 5.
12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156
60 is the answer :)
60 is not divisible by 8.
Please do not answer questions when you don't know the answers.
another way is to prime factorize each number and take the highest power of each prime and multiply them together.
For 8= 2^3 or 2x2x2
for 12=2^2x3 or 2x2x2
for 15=3x5
by taking the highest power of each prime and multiplying together we get our solution:
2^3x3x5 or 2x2x2x3x5 which is 120
To find the least common multiple (LCM) of the numbers 8, 12, and 5, follow these steps:
Step 1: List the prime factors of each number.
8 = 2 x 2 x 2
12 = 2 x 2 x 3
5 = 5
Step 2: Identify the highest power of each prime factor that appears in any of the numbers.
The highest power of 2 is 2^3, as it appears in 8.
The highest power of 3 is 3^1, as it appears in 12.
The highest power of 5 is 5^1, as it appears in 5.
Step 3: Multiply the highest powers of the prime factors together.
2^3 x 3^1 x 5^1 = 8 x 3 x 5 = 120.
Therefore, the LCM of 8, 12, and 5 is 120.
