Question

84 factors
112 factors
196 factors

Answer 1

Step-by-step explanation:

84= 2×42

= 2×2×21

= 2×2×3×7

112= 2×56

= 2×2×28

= 2×2×2×14

= 2×2×2×2×7

196 = 2×98

= 2×2×49

= 2×2×7×7

Answer 2

$\frak{84 = \red2 \times \red2 \times \red3 \times \red7} \\ \\ \frak{112 = \red2 \times \red2 \times \red2 \times \red2 \times \red7} \\ \\ \frak{196 = \red2 \times \red2 \times \red7 \times \red7}$
