Question

Select the GCF of these numbers.
2^5 · 5· 11 and 2^3· 5^2 · 7
2^2 · 3
2· 11^2
3^2
2^3 ·5
13 · 19^3·23^2

Answer 1

Let's just look at \[2^5\cdot5\cdot 7^0\cdot11\]and \[2^3\cdot5^2\cdot7\cdot 11^0\]To get the gcd\gcf you need to take the minimum exponent of each prime. Thus, the gcd/gcf would be\[2^3\cdot5\]
