4) Значит ответ: НОД (81;135) = 3*3*3 = 27

Answer 2

To find the greatest common divisor (НОД) of two numbers, 81 and 135, you can use the Euclidean algorithm.

Step 1: Divide the larger number by the smaller number. 135 ÷ 81 = 1 remainder 54

Step 2: Now, divide the divisor (81) by the remainder (54). 81 ÷ 54 = 1 remainder 27

Step 3: Continue this process until you get a remainder of 0. 54 ÷ 27 = 2 remainder 0

Since the remainder is now 0, the last non-zero remainder was 27. So, the greatest common divisor (НОД) of 81 and 135 is 27.

НОД (81:135) = 27
