Find the value of x,y and z and complete this tree. (View question in attached file.)

Step-by-step explanation:
Given : Prime factorization of x
To Find : Missing values x , y and z
Lets start from bottom
371 = 7 * z
=> z = 53
1855 = 371 * 5 given
y = 1855 * 3 = 5565
x = 2 * y = 2 * 5565 = 11130
x = 11130
y = 5565
z = 53
This is prime factorization of 11130
11130 = 2 * 3 * 5 * 7* 53
Hope this helps..
