Common divisors

Find all common divisors of numbers 30 and 45.

Result

d = (Correct answer is: 1, 3, 5, 15) Wrong answer

Solution:

30=2 3 5 45=32 5  30:1,2,3,5,6,10,15,30 45:1,3,5,9,15,45  d=1,3,5,1530 = 2 \cdot \ 3 \cdot \ 5 \ \\ 45 = 3^2 \cdot \ 5 \ \\ \ \\ 30: 1, 2, 3, 5, 6, 10, 15, 30 \ \\ 45: 1, 3, 5, 9, 15, 45 \ \\ \ \\ d = 1, 3, 5, 15
