1)

${c + cb}^{2}$

$\boxed{c (c+b)}$

2)

$20ax - 5bx - 2by + 8ay$

$5x(4a - b) + 2y( - b + 4a)$

$\boxed{(4a - b)(5x + 2y)}$

3)

${x}^{3} - {x}^{5} - {x}^{7}$

$\boxed{ {x}^{3} (1 - {x}^{2} - {x}^{4} )}$

4)

$2am - 2an + 2a - m + n - 1$

$2a(m - n + 1) - (m - n + 1)$

$\boxed{(m - n + 1)(2a - 1)}$
