Halla el MCM de 63 y 77

Sagot :

Respuesta:

693

Explicación:

Tenemos que dividir ambos dígitos hasta que lleguen a 1.

No importa si uno de los números no se puede dividir, pero se debe iniciar desde los números más bajos: 2, 3, 4, 5, 7...

Cómo no hay una mitad exacta, empezaremos con tercia y continuaremos dividiendo.

63 ; 77 | 3  

21 ; 77  | 3  

7 : 77    | 7

1  ;  11    | 11

1  ;  1

Ahora que llegamos hasta 1, el MCM es la multiplicación de los números por los que hemos dividido a los dígitos. Solo falta multiplicarlos.

3*3*7*11= 693

MCM = 693

Espero te ayude ;)

【Answer.】the lowest common multiple of 77 and 63 is 693.

To obtain the lcm (least common multiple) we must do it by simultaneous decomposition.

This method consists of extracting the common and uncommon prime factors, then

[tex]\large\displaystyle\text{$\begin{gathered}\sf \left.\begin{matrix} \blue{63 \ \ \ 77}\\ 21 \ \ \ 77\\ \ \ 7 \ \ \ 77\\ \ 1 \ \ \ 11\\ \ 1 \ \ \ 1 \end{matrix}\right|\begin{matrix} 3\\ 3\\ 7\\ 11\\ \: \end{matrix} \end{gathered}$}[/tex]

[tex]\sf{m.c.m.(63,77)=3\times3\times7\times11}[/tex]

   [tex]\sf{m.c.m.(63,77)=3^{2} \times7\times11}[/tex]

                 [tex]\boxed{\boxed{\sf{m.c.m.(63,77)=693}}}[/tex]
