Solution Steps

Add 53 and 55 to get 108.

$$108+55+55+58+61+72+77+77+98+\frac{98}{12}$$

Add 108 and 55 to get 163.

$$163+55+58+61+72+77+77+98+\frac{98}{12}$$

Add 163 and 55 to get 218.

$$218+58+61+72+77+77+98+\frac{98}{12}$$

Add 218 and 58 to get 276.

$$276+61+72+77+77+98+\frac{98}{12}$$

Add 276 and 61 to get 337.

$$337+72+77+77+98+\frac{98}{12}$$

Add 337 and 72 to get 409.

$$409+77+77+98+\frac{98}{12}$$

Add 409 and 77 to get 486.

$$486+77+98+\frac{98}{12}$$

Add 486 and 77 to get 563.

$$563+98+\frac{98}{12}$$

Add 563 and 98 to get 661.

$$661+\frac{98}{12}$$

Reduce the fraction \frac{98}{12} to lowest terms by extracting and canceling out 2.

$$661+\frac{49}{6}$$

$$\frac{3966}{6}+\frac{49}{6}$$

Since \frac{3966}{6} and \frac{49}{6} have the same denominator, add them by adding their numerators.

$$\frac{3966+49}{6}$$

Add 3966 and 49 to get 4015.

$$\frac{4015}{6}$$

Factor

$$\frac{5 \cdot 11 \cdot 73}{2 \cdot 3} = 669\frac{1}{6} = 669.1666666666666$$
