_2_x_ _ = 11316 (_ is a missing number)

Question

Please can somebody explain how to do this, thank you

Answer 1

?2? × ??=11316.

First, split 11316 into factors: 2²×3×23×41=11316.

Here are the pairs of factors: (2,5658), (3,3772), (4,2829), (6,1886), (12,943),

(23,492), (41,276), (46,246), (69,164), (82,138), (92,123).

We can eliminate 4-digit factors because we need a 3-digit number and a 2-digit number.

The 3-digit number has 2 as its middle digit. The only solution is 123×92=11316.
