Vampire numbers are the products of two progenitor numbers that when multiplied survive, scrambled together, in the vampire number. Consider one such case: 27×81=2,187. Another vampire number is 1,435, which is the product of 35 and 41. Find others.
Answer
21×60=1,260
15×93=1,395
1,234,554,321 x 9,162,361,086 = 11,311,432, 469,283, 552,606 with others that also work.
