LCM:-

All the terms with highest power is known as LCM...

1)

$\sf \implies \: 25 = 5 \times 5 \\ \\ \: \sf \implies \: 35 = 7 \times 5 \\ \\ \sf \implies \:lcm \: = 5 \times 5 \times 7 = 175$

2)

$\sf \implies \:36 = 3 \times 3 \times 2 \times 2 \\ \sf \implies \:45 = 3 \times 3 \times 5 \\ \\ \sf \implies \:LCM \: \: = 3 \times 3 \times 2 \times 2 \times 5 = 180$

3)

$\sf \implies \:33 = 11 \times 3 \\ \sf \implies \:44 = 11 \times 2 \times 2 \\ \\ \sf \implies \:LCM \: = 11 \times 2 \times 2 \times 3 = 132$

4)

$\sf \implies \:20 = 2 \times 5 \times 2 \\ \sf \implies \:35 = 7 \times 5 \\ \\ \sf \implies \:LCM \: = 7 \times 5 \times 2 \times 2 = 140$

5)

$\sf \implies \:54 = 3 \times 3 \times 3 \times 2 \\ \sf \implies \:38 = 19 \times 2 \\ \\ \sf \implies \:LCM \: = 19 \times 2 \times 3 \times 3 \times 3 \times 2 = 2052$
