Question

Care este cel mai mic numar natural nenul care impartit la 15, 12, respectiv 20, dar restul 10?

Answer 1

12*15*20+10 = 3610
pr  3610 : 12 = 30 rest 10
      3610 : 15 = 24 rest 10
      3610 : 20 = 18 rest 10

Answer 2

x:15=c1 rest 10
x=M₁₅ +10

x:12=c2 rest 10
x=M₁₂ +10

x:20=c3 rest 10
x=M₂₀+10

x=[M₁₅;M₁₂;M₂₀]+10

15=3*5
12=2² *3
20=2² *5
[15;12;20]=3 *5 *2²= 15*4=60

x-cel mai mic
x=60*1+10=60+10=70
