$$300\times 7\times 8\times 9\times 10\times 11\times 12+\frac{123045678}{10}$$

Multiply 300 and 7 to get 2100.

$$2100\times 8\times 9\times 10\times 11\times 12+\frac{123045678}{10}$$

Multiply 2100 and 8 to get 16800.

$$16800\times 9\times 10\times 11\times 12+\frac{123045678}{10}$$

Multiply 16800 and 9 to get 151200.

$$151200\times 10\times 11\times 12+\frac{123045678}{10}$$

Multiply 151200 and 10 to get 1512000.

$$1512000\times 11\times 12+\frac{123045678}{10}$$

Multiply 1512000 and 11 to get 16632000.

$$16632000\times 12+\frac{123045678}{10}$$
