Какой у тебя вопрос?

НОД (20;48) - это Наибольший Общий Делитель , или самое большое число, на которое можно делить и 20 и 48

Сначала разложим на простые множители 20 и 48 (то есть делим на 2 столько раз, сколько делится, потом на 3, 5, 7, 11, 13 - это простые множители)

20:2=10 10:2=5 5:5 =1 , то есть

20=2*2*5 - это разложение 20 на простые множители, теперь 48

48:2=24 24:2=12 12:2=6 6:2=3 3:3=1, значит

48=2*2*2*2*3

еще раз выпишу разложение на простые множители

20=2*2*5,

48=2*2*2*2*3, теперь выписываем те общие множители, которые есть и у 48 и 20, а общее у них - это по две двойки, значит

2*2 = 4 - это НОД для 20 и 48

НОД(20;48) = 2*2 =4

2. НОД(28;40)= 2*2=4

28=2*2*7

40=2*2*2*5 (общее - 2*2 =4)

Сравниваем

НОД(20;48) = 4 НОД(28;40) = 4

НОД(20;48)=НОД(28;40)
