please solve for impairment loss

Purchase Company recently acquired several businesses and recognized goodwill in each acquisition. Purchase has allocated the resulting goodwill to its three reporting units: RU-1, RU-2, and RU-3. Purchase opts to skip the qualitative assessment and therefore performs a quantitative goodwill impairment review annually. In its current-year assessment of goodwill, Purchase provides the following individual asset and liability carrying amounts for each of its reporting units: The total fair values for each reporting unit (including goodwill) are $674,350 for RU-1, $720,400 for RU-2, and $765,650 for RU-3. To date, Purchase has reported no goodwill impairments. How much goodwill impairment should Purchase report this year for each of its reporting units
