Question

C.m..m.m.c al nr:210 240 280este:

Answer 1

^=putere
*=ori
noua ne trebuie cel mai mic multiplu comun al numerelor (cmmmc)
210=2*3*5*7
240=2^4*3*5
280=2^3*5*7
Se iau toti factorii primi, la puterile cele mai mari.
cmmmc (210,240,280)=2^4*3*5*7=1680

Answer 2

210=2*3*5*7
240=2⁴*3*5
280=2³*5*7
[210;240;280]=2⁴ * 3 * 5 * 7 =1680
