Solution 2:

(a):

2\times1768\times502×1768×50

=\left(2\times50\right)\times1768(2×50)×1768

=\left(100\times1768\right)(100×1768)

=176800

Solution (b):

4\times166\times254×166×25

=\left(4\times25\right)\times166(4×25)×166

=100\times166100×166

=16600

Solution (c)

8\times125\times2918×125×291

=\left(8\times125\right)\times291(8×125)×291

=1000\times2911000×291

=291000

Solution(d):

625\times279\times16625×279×16

=\left(625\times16\right)\times279(625×16)×279

=10000\times27910000×279

=2790000

Solution (e):

285\times5\times60285×5×60

=\left(5\times60\right)\times285(5×60)×285

=300\times285300×285

=85500

Solution(f):

125\times40\times8\times25125×40×8×25

=\left(40\times25\right)\times\left(125\times8\right)(40×25)×(125×8)

=1000\times10001000×1000

=1000000
