Hi Pankaj,
  We can do so as shown below..

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

<xsl:output method="text" />

<xsl:variable name="number" select="5" />

<xsl:template match="/">
  <xsl:call-template name="factorial">
    <xsl:with-param name="number" select="$number" />
  </xsl:call-template>
</xsl:template>

<xsl:template name="factorial">
  <xsl:param name="number" />

  <xsl:choose>
    <xsl:when test="$number = 1">
      1
    </xsl:when>
    <xsl:otherwise>
      <xsl:variable name="x">
        <xsl:call-template name="factorial">
           <xsl:with-param name="number" select="$number - 1" />
        </xsl:call-template>
      </xsl:variable>
      <xsl:value-of select="$number * $x" />
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

</xsl:stylesheet>

Regards,
Mukul
