Question

1. Si
A = MCM(420; 300)
B = MCM(15; 8)
calcule A +B.​

Answer 1

Respuesta:

330

Explicación paso a paso:

Hallamos A :

A = MCM(420; 300)

420 - 300 | 2

210 - 150 | 2

105 - 75 | 3

35 - 25 | 5

7 - 5 | 5

7 - 1 | 7

1 - 1        

A =M.C.M (420,300) = 2² × 3 × 5² × 7

A =M.C.M (420,300) = 2100

A = 2100

Hallamos B :

B = MCM(15; 8)

15 - 8 | 2

15 - 4 | 2

15 - 2 | 2

15 - 1 | 3

5 - 1 | 5

1 - 1  

B = M.C.M (15,8) = 2³ × 3 × 5

B = M.C.M (15,8) = 120

B = 120    

Hallamos A + B:

A + B

210 + 120
