The factors of HCF can be seen as 'compulsory factors' in the two numbers (5^2 x 7).The factors of LCM can be seen as 'additional factors' (2^3 and 3^2).
I split the 'additional factors' into two numbers instead of all into one because this would make one of the numbers = 175 (seen in other combination 1)
Students also ask whether they can put like x2 / x3 in other number. But this will lead to HCF being not equal to 175 (seen in other combination 2)
Hope this helps! ;))
