Answer 1

Answer:

Step-by-step explanationSteps to find LCM

Find the prime factorization of 810

810 = 2 × 3 × 3 × 3 × 3 × 5

Find the prime factorization of 1080

1080 = 2 × 2 × 2 × 3 × 3 × 3 × 5

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 2 × 3 × 3 × 3 × 3 × 5

LCM = 3240
