(a) 2 × 1768 × 50 (b) 4 × 166 × 25

(c) 8 × 291 × 125 (d) 625 × 279 × 16

(e) 285 × 5 × 60 (f) 125 × 40 × 8 × 25

(a) 2×1768×50

Arrange it in increasing order,

= 2×50×1768

= 100×1768

= 176800

(b) 4×166×25

Arrange it in increasing form,

= 4×25×166

= 100×166

= 16600

(c) 8×291×125

= 8×125×291

= 1000×291

= 291000

(d) 625×279×16

= 625×16×279

= 10000×279

= 279000

(e) 285×5×60

= 285×300

= 85500

(f) 125×40×8×25

= 125×8×40×25

= 1000×1000

= 1000000
