Hi ,

if a,b ,c are integers

ab + ac = a ( b+ c ) is distributive property.

125 × 8 × 883 + 117 × 25 × 40

= ( 125 × 8 ) × 883 + 117 × ( 25 × 40 )

= 1000 × 883 + 117 × 1000

a = 1000 , b = 883 , c = 117

= 1000 ( 883 + 117 )

= 1000 × 1000

= 1000000

688×10×437-6880×337

= 6880×437-6880×337

=6880×[437-337]

=6880x100

=688000

hope it helps u
