Any factor of this number should be of the form 53^a * 73^b * 7^c * 5^d * 2^e * 3^f.
For the factor to be an even number e should be non zero.
a can take values 0, 1
b can take values 0, 1
c can take values 0, 1, 2, 3
d can take values 0, 1, 2
e can take values 1, 2, 3, 4
and f can take values 0, 1, 2, 3, 4

Solution
The first letter of the given series is formed by adding 2 letters
So H+2 = J, J+2 = L, L+2= N, N+2 = P
2nd letter is formed in the revers direction by subtracting 4 letters
So Y - 4 = U, U - 4 = Q, Q - 4 = M, M - 4 = I
