Final answer:
The GCF of 16s³t, 40s5, and 68t² is 4s³t.
Step-by-step explanation:
In order to find the GCF (Greatest Common Factor) of the given terms: 16s³t, 40s5, and 68t², we need to factorize each term and find the common factors.
16s³t can be written as 2 * 2 * 2 * 2 * s * s * s * t.
40s5 can be written as 2 * 2 * 2 * 5 * s * s * s * s * s.
68t² can be written as 2 * 2 * 17 * t * t.
The factors that are common to all three terms are 2 * 2 * s * s * s * t, which can be simplified as 4s³t. Therefore, the GCF of 16s³t, 40s5, and 68t² is 4s³t.
