The first two consecutive numbers to have two distinct prime factors are:

• 14 = 2 x 7
• 15 = 3 x 5

The first three consecutive numbers to have three distinct prime factors are:

• 644 = 2² x 7 x 3
• 645 = 3 x 5 x 43
• 646 = 2 x 17 x 19

Find the first four consecutive integers to have four distinct prime factors each. What is the first of these numbers?
