Greatest Common Factor of 80 and 5005 by prime factorization method
We will first find the prime factorization of 80 and 5005.
Prime Factorization of 80 is 1, 2, 2, 2, 2, 5 and Prime Factorization of 5005 is 1, 5, 7, 11, 13.
- Factorize\( (80) = \) \(1\times 2\times 2\times 2\times 2\times 5\)
- Factorize\( (5005) = \) \(1\times 5\times 7\times 11\times 13\)
Now we need to find any which are common for each number (1, 5) and multiply these numbers together.
\(GCF(80, 5005) = 1\times 5 = 5\).
Greatest Common Factor of 80 and 5005 by matching factors method
