Answer 2

Answer:

LCM(112,140&168)=1680

Step-by-step explanation:

Step-1: Express given numbers (112,140,168) in their exponential forms.

112=2⁴×7¹

140=2²×5¹×7¹

168=2³×3¹×7¹

Step-2: Take every base from their exponential forms.

2⁰×3⁰×5⁰×7⁰

Step-3: Assign the respective greatest exponent to each of the base from their exponential forms.

2⁴×3¹×5¹×7¹

Step-4: Take the product of the above.

16×3×5×7=48×5×7

=240×7

=1680

Therefore, LCM(112,140,168) =1680
