## What is the LCM of 24 15 and 36?

LCM of 24, 15 and 36 = 360 [LCM of two or more numbers = product of the greatest power of each prime factor involved in the numbers, with highest power.]

## What is the LCM of 15 and 20?

Least common multiple (LCM) of 15 and 20 is 60.

## Is 91 a prime number Yes or no?

91 is a Prime or Composite Number So 91 is a composite number because composite numbers have factors more than 2. Here we get four factors for 91 and they are 1, 13, 7, 91. As the total number of factors are more than two it satisfies the condition of composite number. Hence 91 is a composite number.
