There are 2 sig figs in 460. In this case, the 4 and the 6 are significant. All nonzero numbers are significant, so in 123.45, there are five sig figs. Also, all zeros in front of a number without a decimal point in front of them are insignificant, so in 00460, there would still be just two sig figs.
