Answer 2

Highest common factor of $513$ and $783$ is $27$

Step-by-step explanation:

Given,

Find HCF of $513$ and $783$ by using prime factorization method.

∴ $513=3\times 3\times 3\times 3\times 19$

Factor of $513$ is $3,3,3,3 and 19$

And $783=3\times 3\times 3\times 29$

Factor of $783$ is $3,3,3 and 29$

∴ Common factor of  $513$ and $783$ are $3,3 and 3$

∴ Highest common factor of $513 and 783=3\times 3\times 3=27$
