Find the least common multiple of these two expressions. 10v^6y^7 and 6w^4v^5y^3

10v⁶y⁷    = 2 * 5 * *      

6w⁴v⁵y³ = 2 * 3 * * * yyy

GCF: 2v⁴y³

The LCM is the GCF and everything leftover

LCM: 2v⁴y³ * (5 * v * ) * (3 * )

       = (2 * 5 * 3) * (v⁴ * v) * (w⁴) * (y³ * y⁴)

       =        30           v⁵        w⁴        y⁷

LCM =  30v⁵w⁴y⁷

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

one set of data has more variation than the other. hope this !
