Step 1.
Find the common factors.
[tex]28m = 2 \times 2 \times 7 \times m[/tex]
[tex]42 = 2 \times 3 \times 7[/tex]
The common factors are 2 and 7. Two times seven is 14. Therefore their factor is 14.
Step 2.
Divide 14 to the two terms.
[tex]28m \div 14 = 2m[/tex]
[tex]42 \div 14 = 3[/tex]
Step 3.
Rewrite the equation.
[tex]14(2m + 3 )[/tex]
Therefore, the factored form of the equation 28m+42 is 14(2m+3).
