Final answer:
In using Euclid's division algorithm to find the HCF, Tina's division of 616 by 32 suggests that 616 is a and 32 is b. The HCF will be found through subsequent divisions until the remainder is zero.
Step-by-step explanation:
Tina is trying to find the highest common factor (HCF) of two numbers, a and b, using Euclid's division algorithm. At one point, she divides 616 by 32. Euclid's algorithm begins with two positive numbers and repeatedly applies the rule that the HCF of two numbers also divides their difference.
Here, the division of 616 by 32, with a remainder, suggests that 616 is a, and 32 is b, with a being the larger number and b being the potential factor.
From Euclid's algorithm, it can be understood that in the step where Tina divides 616 by 32, the algorithm requires her to continue this process using 32 and the remainder from the division until the remainder is zero.
The non-zero remainder that immediately precedes the zero remainder will be the HCF of a and b.
