Detailed Solution

We have been given the numbers 280 and 1245.
Remainder = 4 and 3.
Subtracting 4 and 3 from 280 and 1245 respectively.
This will give us two new numbers, i.e., 276 and 1242.
Prime factors of 276 and 1242,

276 = 2 \times 2 \times 3 \times 23 = 2^{2} \times 3^{1} \times 23^{1}

1242 = 2 \times 3 \times 3 \times 3 \times 23 = 2^{1} \times 3^{3} \times 23^{1}

Calculating the HCF of 276 and 1242,

{\Rightarrow 2^{1} \times 3}^{1} \times 23^{1}

\Rightarrow 138

Therefore, the given statement is true.
Hence, option 1 is correct.
