Tāpirihia te 2 ki te 1, ka 3.

$$3\left(2^{2}+1\right)\left(2^{4}+1\right)\left(2^{8}+1\right)$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$3\left(4+1\right)\left(2^{4}+1\right)\left(2^{8}+1\right)$$

Tāpirihia te 4 ki te 1, ka 5.

$$3\times 5\left(2^{4}+1\right)\left(2^{8}+1\right)$$

Whakareatia te 3 ki te 5, ka 15.

$$15\left(2^{4}+1\right)\left(2^{8}+1\right)$$

Tātaihia te 2 mā te pū o 4, kia riro ko 16.

$$15\left(16+1\right)\left(2^{8}+1\right)$$

Tāpirihia te 16 ki te 1, ka 17.

$$15\times 17\left(2^{8}+1\right)$$

Whakareatia te 15 ki te 17, ka 255.

$$255\left(2^{8}+1\right)$$

Tātaihia te 2 mā te pū o 8, kia riro ko 256.

$$255\left(256+1\right)$$

Tāpirihia te 256 ki te 1, ka 257.

$$255\times 257$$

Whakareatia te 255 ki te 257, ka 65535.
