Here $$23794206$$ and $$23756819$$ are both $$8-$$digits numbers in which the same numbers $$2,3$$ and $$7$$ are placed ten lakhs, lakhs, ten thousands, thousands and hundreds places respectively whereas $$9$$ and $$5$$ are placed at tens place respectively.
Since $$9 > 5$$
Therefore $$23794206 > 23756819$$
Here $$5032786$$ and $$5032790$$ are both $$7-$$digits numbers in which the same numbers $$5,0,3,2$$ and $$7$$ are Placed at ten lakhs, lakhs, ten thousands, thousands and hundreds places respectively whereas $$9$$ and $$8$$ are placed at tens place respectively.
Since $$9 > 8$$
Therefore $$5032790 > 5032786$$
$$987876$$ is a $$6-$$digits number
The given numbers in the descending order are:
$$23794206 > 23756819 > 5032790 > 5032786 > 987876$$
