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)

My friends and I have a very good time in the Park. We have a lot of fun. There is an ice cream parlor here. There are chocolate, strawberries, etc. there are many different carousels in the Park. We went around almost everyone. And even on some of them twice. There are carousels for both young children and older children. There is also a Museum of paintings in the Park. There are very interesting, original and beautiful paintings and photos. There is also a mini Aqua Park in the Park. It's also very fun.
