★In the form of Steps =>

i)Find the prime factorization of

400 →

400 = 2 × 2 × 2 × 2 × 5 × 5

ii)Find the prime factorization

of 1080 →

1080 = 2 × 2 × 2 × 3 × 3 × 3 ×

5

iii)Multiply each factor the

greater number of times it

occurs in steps i) or

ii) above to find the LCM:

LCM = 2 × 2 × 2 × 2 × 3 × 3 × 3

× 5 × 5

iv)LCM = 10800
