Question

Write all the composite numbers less than $10$. Find their product and express it as the product of prime numbers

Answer 1

$4,6,8,$ and $9$ are the composite numbers less than $10$.

Required product is $4\times 6\times 8\times 9=1728$

$1728$ can be expressed as the product of prime numbers as:

$1728=2\times 2\times 2\times 2\times 2\times 2\times 3\times 3\times 3$
