Solution:

package main

func main() {
    var i, j, k, ki, ij int
    result := 1.0
    for i = 1; i < 10; i++ {
        for j = 1; j < i; j++ {
            for k = 1; k < j; k++ {
                ki = 10*k + i
                ij = 10*i + j
                if ki*j == ij*k {
                    result *= float64(ij) / float64(ki)
                }
            }
        }
    }
    println(int(result))
}

Result: 100
