Question

calcule :

a) mmc( 2^2. 3^3.5^2 , 2. 5^2.7^3)

b) mmc(14,36)

c) mmc(16,42,54)

Answer 1

Bom tarde

a) mmc ( 2^2. 3^3 * 5^2 , 2. 5^2 * 7^3)

mmc = 2^2 * 3^3 * 5^2 * 7^3 = 926100

b) mmc(14,36)

14 36 2

mmc = 2^2 * 3^2 * 7 = 4*9*7 = 252

c) mmc(16,42,54)

16 42 54 2

8 21 27 2

4 21 27 2

2 21 27 2

1 21 27 3

mmc = 2^4 * 3^3 * 7 = 3024
