Question

Сколько будет НОД (30;12) заранее спасибо

Answer 1

Наибольший общий делитель для 30 и 12 равен 6 
Как найти НОД?
надо разложить на простые множители данные числа.
30=2*3*5
12=2*2*3
Теперь выбираем, те множители которые повторились в обеих числах и перемножим их, это и будет НОД.
У нас повторились 2 и 3 значит НОД = 2*3=6

Answer 2

6 - правильный ответ на задание))

Answer 3

Calculating the Greatest Common Divisor (GCD)

To find the greatest common divisor (GCD) of 30 and 12, we can use various methods such as prime factorization, Euclidean algorithm, or simply listing the factors. Let's use the Euclidean algorithm to calculate the GCD.

The Euclidean algorithm states that the GCD of two numbers can be found by repeatedly applying the division algorithm until the remainder is 0. The divisor at this step is the GCD of the original two numbers.

Euclidean Algorithm: 1. Divide 30 by 12: 30 ÷ 12 = 2 with a remainder of 6. 2. Divide 12 by 6: 12 ÷ 6 = 2 with a remainder of 0.

Since the remainder is 0, the GCD of 30 and 12 is the divisor at this step, which is 6.

Conclusion

Therefore, the greatest common divisor (GCD) of 30 and 12 is 6.
