Find all the prime factors of the three numbers. pick up the common factors, ONCE, then pick up the non-common factors one by one, multiply the factors, the product is the least common factor.
example: the least common multiple of 6, 8, and 15
6=2*3
8=2*2*2
15=3*5
Note: do not write 8 into 4*2, because 4 is not a prime number. you have to break the number down to prime factors only.
Notice that 6 and 8 have a common factor 2, so pick up the 2;
6 and 15 have a common factor of 3, so pick up the 3.
those are the only two shared factors, so 2×3
now pick up whatever is not shared:
the two 2s for 8 and the 5 for 15 is not shared, add 2, 2, and 5 to the multiplication: 2×3×2×2×5=120
120 is the least common multiples of 6,8, and 15
this is basically how it is done. I believe you can explain better in your own words.
Answer:
320
Step-by-step explanation:
With regards to the above, if a 16 year old person who earns $8,000 makes 64 posts in a week, what is the value of k.
We can find the value of k to be;
64 = (√16)/(3√8,000) . k
= 4/20 . k
= 1/5 . k
= 0.2k
K = 64 × 5
K = 320
Answer: Second option, third option and fifth option.
Step-by-step explanation:
In order to solve this exercise it is important to remember the multiplication of signs:
Knowing that, you can distribute the sign and add the like terms. Repeat this procedure in each expression given in the exercise.
Therefore, you get:
You can identify that the expressions , and are equivalent after simplifying.
Answer:
a. 2 b. 12 c. 36 d. 19
James makes $1,250.
a. (2+8)+9 b. (3+7)+5+4 c. (4+16)+2 d. (31+9)+4
Step-by-step explanation:
You basically follow PEMDAS for the first section. You would do the subtraction inside the parenthesis first and then you will subtract left to right as you go.
You will add up all of the things he has on his budget to find out how much he earns.
I believe that is correct but I am not sure.
Hope it helps! (:
I didn’t read the question right sorry
