LCM of 7 and 13

Since 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.

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

The numbers do not have a factor in common (they are relatively prime) so the LCM is the product. 7*13=91 ■
