$345\,675 \times 54$
345\,675 \times 54 = (345\,675 \times 50) + (345\,675 \times 4)
17\,283\,750 + 1\,382\,700 = 18\,666\,450
$543\,765 \times 28$
543\,765 \times 28 = (543\,765 \times 20) + (543\,765 \times 8)
10\,875\,300 + 4\,350\,120 = 15\,225\,420
$653\,213 \times 49$
653\,213 \times 49 = (653\,213 \times 40) + (653\,213 \times 9)
26\,128\,520 + 5\,878\,917 = 32\,007\,437
$843\,213 \times 32$
843\,213 \times 32 = (843\,213 \times 30) + (843\,213 \times 2)
25\,296\,390 + 1\,686\,426 = 26\,982\,816
