Answer 1

Answer:

don't know

but give me only thanks

Answer 2

Answer:

Step-by-step explanation:

The least common multiple of 40 and 65 can be computed by using the greatest common factor aka gcf of 40 and 65. This is the easiest approach:

lcm (40,65) =  

 

 

= 520

Alternatively, the lcm of 40 and 65 can be found using the prime factorization of 40 and 65:

The prime factorization of 40 is: 2 x 2 x 2 x 5

The prime factorization of 65 is: 5 x 13

Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(40,40) = 520

In any case, the easiest way to compute the lcm of two numbers like 40 and 65 is by using our calculator below. Note that it can also compute the lcm of more than two numbers, separated by a comma. For example, enter 40,65. Push the button only to start over.

First we will find the hcf. Since 65>45

Therefore, 64=40×1+25 40=25×1+15 25=15×1+10 15=10×1+5 10=5×2+0

Since remainder is 0

Therefore hcf is 5 .
