Question

HCF of $100$ and $4423$ is ?

Answer 1

Solve for the H.C.F:

Use the prime factorization

$$\begin{gathered} 100=2\times 2\times 5\times 5 \\ 4423=1\times 4423 \end{gathered}$$

Since, no prime factors are common in both the numbers so, the H.C.F. is $1$.

Hence, the H.C.F. of the numbers $100$ and $4423$ is $1$.
