What is the LCM of two numbers that have no common factors greater than 1?

This question was already answered before. I'm going to post someone else's answer with credit given of course:

"<span>The answer is their product. The least common multiple (LCM) is the smallest number which is a multiple of two numbers. If two numbers have no common factors greater than 1, then their LCM will be their product. For example, take numbers 7 and 9. They have none common factor greater than 1. So, LCM will be 7 * 9 = 63." - @W0lf93

Not sure if this answers your question, but hope this helped...</span>

The numbers are m and n where m and n have no common factors

to find the LCM, factor them and group the common factors

since m and n have no common factors
m=1*m
n=1*n
LCM=1*m*n=mn

the LCM of 2 numbers with no common factors greater than 1 is the product of the 2 numbers

Suppose commute times in a large city are normally distributed and that 63.70% of commuters in this city take more than 22 minut

USPshnik [31]

Answer:

The mean is 24.205

Step-by-step explanation:

Firstly, we need to get the z-score

From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way

So the probability we had was;

P( x > 22)

So we need the z-score corresponding to 63.70% or simply 0.637

We can use the standard normal distribution table to get this

Mathematically, from the standard normal distribution table this is -0.35

z-score = (x- mean)/SD

-0.35 = (22-mean)/6.3

22-mean = -2.205

mean = 22 + 2.205 = 24.205
