Calculando o MMC

Letra A)

$mmc(180,84)= \:?$

Dividindo os números por fatores primos:

$180,84 \div 2$

$90, 42 \div 2$

$45, 21 \div 3$

$15, 7 \div 3$

$5, 7 \div 5$

$1, 7 \div 7$

$1, 1$

Calculando:

$mmc(180,84)=2^2 \times 3^2 \times 5 \times 7$

$mmc(180,84)=1260$

Letra B)

$mmc(375,225) =\: ?$

$375, 225 \div 3$

$125, 75 \div 3$

$125, 25 \div 5$

$25, 5 \div 5$

$5, 1 \div 5$

$1, 1$

Logo,

$mmc(375, 225) =3^2 \times 5^3$

$mmc(375,225)=1125$

Letra C)

$mmc(96,144,240)= \: ?$

$96, 144, 240 \div 2$

$48, 72, 120 \div 2$

$24, 36, 60 \div 2$

$12, 18, 30 \div 2$

$6, 9, 15 \div 2$

$3, 9, 15 \div 3$

$1, 3, 5 \div 3$

$1, 1, 5 \div 5$

$1, 1, 1$

Logo,

$mmc(96, 144, 240)=2^5 \times 3^2 \times5$

$mmc(96, 144, 240)=1440$
