    Can anyone pleasee help me find the 5th Testcase issue or an error in my code? That is the only one failing:

    fun main(args: Array<String>) {
    val t = readLine()!!.trim().toInt()

    for (tItr in 1..t) {
        val n = readLine()!!.trim().toLong()
        getLargePrime(n)
    }
}

private fun getLargePrime(n: Long){
    /*
        large = 0
        check prime and large than small, assign
    */
    var i = 2L
    var number = n
    var large = 0L
    while (i <= number) {
        if (number % i == 0L) {
            if(large < i) large = i            
            number /= i
            i--
        }
        i++
    }
    println(large)
}
