Greatest Common Factor of 1616 and 2020 by prime factorization method
We will first find the prime factorization of 1616 and 2020.
Prime Factorization of 1616 is 1, 2, 2, 2, 2, 101 and Prime Factorization of 2020 is 1, 2, 2, 5, 101.
- Factorize\( (1616) = \) \(1\times 2\times 2\times 2\times 2\times 101\)
- Factorize\( (2020) = \) \(1\times 2\times 2\times 5\times 101\)
Now we need to find any which are common for each number (1, 2, 2, 101) and multiply these numbers together.
\(GCF(1616, 2020) = 1\times 2\times 2\times 101 = 404\).
Greatest Common Factor of 1616 and 2020 by matching factors method
