Answer 2

I can help you with your math question. НОД stands for наибольший общий делитель, which means the greatest common divisor in English. To find the НОД of two numbers, you can use the Euclidean algorithm, which repeatedly divides the larger number by the smaller number and takes the remainder as the new smaller number, until the remainder is zero. The last non-zero smaller number is the НОД. For example:

НОД(13;26) = НОД(26;13) = НОД(13;0) = 13

НОД(65;66) = НОД(66;65) = НОД(65;1) = НОД(1;0) = 1

НОД(42;35) = НОД(35;42) = НОД(42;35) = НОД(35;7) = НОД(7;0) = 7

Therefore, the answer is:

НОД(13;26) + НОД(65;66) + НОД(42;35) = 13 + 1 + 7 = 21

I hope this helps you understand the concept of НОД. If you have any other math questions, feel free to ask me. I can also generate some practice problems for you if you want. Have a nice day!Ответь+подробно.+Найдите:НОД(13;26)+НОД+(65;66)+НОД+(42;35)
