What is the LCM of 13 and 7?

LCM of 7 and 13Since 7 and 13 are both prime numbers, or numbers whose only factors are 1 and itself, the LCM can be found by multiplying 7 and 13 together. The answer will be 91.Though multiplying the numbers together when working with composite numbers MIGHT work, it only works 100% of the time when both numbers are prime. If one or both numbers are composite (have more factors than 1 and itself), multiples should be listed until a common one is found. That number will be the LCM.The LCM of 7 and 13 is 91.
