lcm 3m^2,-4m^2,-7m^2,2m^2

lcm

3 m^{2}, - 4 m^{2}, - 7 m^{2}, 2 m^{2}

- 84 m^{2}

Solution steps

Find Least Common Multiplier of

3 m^{2}, - 4 m^{2}, - 7 m^{2}, 2 m^{2}

Factor

3 m^{2}

3 \cdot m^{2}

Factor

- 4 m^{2}

- 2^{2} \cdot m^{2}

Factor

- 7 m^{2}

- 7 \cdot m^{2}

Factor

2 m^{2}

2 \cdot m^{2}

Multiply each factor with the highest power:

- 2^{2} \cdot 3 \cdot 7 \cdot m^{2}

Simplify

- 84 m^{2}

x^{2} - 3 x - 4, x^{2} - 8 x + 15

3 a + 2 b - c, 2 a + 3 b + c

2 x^{2} - 9 x, 5 - 3 x

5 x^{6} \cdot (x^{4} - 3 x^{2}), 8 x^{4} \cdot (3 x^{3} - 4 x^{4})

x^{2} - 4 x, - 7 x + 6, 3 x^{2} - 5
