Question

Qual é o mdc de 48,60

Answer 1

take the MDC is the same as taking the MMC. The only difference when the factorization of MDC is that the numbers, for example 48 and 60, must be divisible simultaneously by two numbers, this means that when the two numbers are not divisible at the same time, there to; since the MMC when these numbers, for example 48 and 60, are undivided while factoring then be individually. Thus we have: 

MDC (48.60) ⇒ 48, 60 Ι 2 (48 and 60 are divisible both by 2) 
                           24, 30 Ι 2 (24 and 30 are also divisible both by 2) 
                            12, 15 Ι 3 (See I can not for the number 2) 
                              4, 5 Ι (there is no number divisible by both 4 and 5) 
                                         Ι 
    Therefore, the MDC (48.60) = 2 * 2 * 3 = 12 ⇒ M ⇒DC (48.60) = 12. Ready! It is not simple?
