Numerical train 2

The 'Numerical Train-2' is a train for the factors of composite number '780' where J's conveying Jumps relate to 'multiplication' on LHS and
J's on RHS relate to 'division ' . Similarly , W 's conveying Walks on L H S relate to 'addition' and W 's on R H S relate to ' subtraction ' .
The count of W = +1 on L H S and on R H S , W = - 1 . Two factors of
780 conveyed by J's on L H S are already given . The goal is to find
out other three factors indicated by J's on R H S of number ' 780 ' .
Logic of the puzzle is that ' number - train ' exactly returns any integer
selected for variable ' x ' after other three factors are calculated .
For variable ' x ' , the train for number ' 780 ' is indicated as
L H S R H S * 30 +1 * 26 - 1 / ? -1 / ? -1 / ? - 1 x J W J W J W J W J W = x 30 x 30 x+1 780 x+26 780 x+25

So , find out the other three factors of value ' 780 ' where the algebraic
term ' 780 x+25 ' imparts the variable ' x ' selected for any integer . DETAILS : The values ' 30 ' and ' 26 ' are factors of ' 780 ' ( constants ) on L H S and ' x ' is a variable . Other three factors ( constants ) should be calculated
