Answer

Problem

By multiplying which factors the result will be 182.

Step:

We look for pairs of numbers that multiply together to give

182

Clue

Product means Multiplication

\$ \times \$

Step:

Multiply the number 14 by 13

\$14 \times 13\$

Step:

After the multiplication, we get

\$182\$

Choice.A

This option results in 182, not 169, So this option is incorrect

13 x 13

Choice.B

The product of these factors is 14 × 13 = 182, which matches the desired result. Hence, this is the correct answer

14 x 13

Choice.C

The product of these factors is 14 × 13 = 182, which is not equal to 195. Thus, option C is incorrect

15 x 13

Choice.D

14 × 13 = 182 This option results in 182, not 208. So it’s incorrect

16 x 13
