10x^7 = 10x^4 * x^3

50x^4 = 10x^4 * 5

LCM = 10x^4 * 5x^3 = 50x^7

x^2 - 36 = (x+6)(x-6)

x^2 + 11x + 30 = (x+6)(x+5)

LCM = (x+6)(x-6)(x+5)

y^3 + 8y^2 + 16y = y(y+4)(y+4)

y^2 - 8y = y(y-8)

LCM = y(y+4)(y+4)(y-8)

15z^2 + 60z = 15z(z+4) = 3(z+4)*5z

3z^2 + 15z + 12 = 3(z+4)(z+1)

LCM = 15z(z+4)(z+1)
