Array formula in cell D11:

=MAX(IF((COUNTIF(Table1[Value],Table1[Value])<>1)+(Table1[Value]=””),””,Table1[Value]))

Array formula in cell D12:

=LARGE(IF((COUNTIF(Table1[Value],Table1[Value])<>1)+(Table1[Value]=””),””,Table1[Value]),100)

Formula in cell D15:

=MAX(Table1[Value])

Formula in cell D16:

=MIN(Table1[Value])

Array formula in cell G11:

=LARGE(IF((COUNTIF(Table1[Value],Table1[Value])<>1)+(Table1[Value]=””),””,Table1[Value]),ROW(A1))

Explaining array formula in cell D11

Step 1 – Count the number of cells within a range that meet a given condition

COUNTIF(Table1[Value],Table1[Value])

returns

{1;1;1;0;1;1;1;1;1;…}

Step 2 – Check if value in array is a duplicate

COUNTIF(Table1[Value],Table1[Value])<>1

becomes

{1;1;1;0;1;1;1;1;1;…}<>1

and returns

{FALSE;FALSE;FALSE;TRUE;FALSE;FALSE;FALSE;FALSE;FALSE;…}

 Step 3 – Check if table value is a blank

(Table1[Value]=””)

returns

{FALSE;FALSE;FALSE;TRUE;FALSE;FALSE;FALSE;FALSE;FALSE; …}

Step 4 – Return table value if conditions are met

IF((COUNTIF(Table1[Value],Table1[Value])<>1)+(Table1[Value]=””),””,Table1[Value])

becomes

IF({FALSE;FALSE;FALSE;TRUE;FALSE;FALSE;FALSE;FALSE;FALSE; …}, “”, {72;373;230;0;311;424;460;418;665})

and returns

{72;373;230;””;311;424;460;418;665;…}

Step 5 – Return max value

MAX(IF((COUNTIF(Table1[Value],Table1[Value])<>1)+(Table1[Value]=””),””,Table1[Value]))

becomes

=MAX({72;373;230;””;311;424;460;418;665;…})

and returns 694 in cell D11.
