Ответ:75

Пошаговое объяснение:Если НОК чисел делится на столько, во сколько раз больше одно число больше чем другое без остатка- значит что НОК и результат деления являются этими двумя числами

1)60:4=15

2)15+60=75

Проверка: 15=(3)*(5)

60=2*2*(3)*(5)

В скобках повторяющиеся цифры

НОК(15,60)=2*2*3*5=60

elmiraabisheva1987: Правильно 75

svetlanahegai: поч?
