find the values using suitabe properties :

1487 x 327 x (-487) x 327 =

The above given expression seems to be incorrect, it should be:

1487 $\times$ 327 + (-487) $\times$ 327

so, we take 327 common, using distributive law of multiplication over addition

= 327 $\times$ (1487 + (- 487))

= 327 $\times$ (1487 - 487)

= 327 $\times$ (1000)

= 327000 (answer)
