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)
