How do you do lcm and how do you slove the lcm of 32,40,36

To solve the least common factor you need to find the lowest numbers that all three numbers can go into.  So for 32, 36, and 40.  You would have to multiply.  The final answer would be 1440.

£116.67

Step-by-step explanation:

Given;

Nar donated to 4 charities last year. She gave £175 to each of these charities.

The total amount Nar donated is;

Nar = 4 × £175 = £700

For Rana to donate the same amount equally among 6 charity, to determine the amount each charity would receive this year, we need to divide the total amount by the number of charities;

A = £700/6

A = £116.67
