Prime factors of 42: 2x7x3
prime factors of 126: 2x3x3x7
prime factors of 210: 7x3x5x2
now we multiply all the factors that they all have in common: 2x3x7 which is 42. So the highest common factor is 42

Answer:
(A) yes; each small square could represent 10 units
(B) no; there are a total of 14 small squares. No reasonable relationship maps this to 410
Step-by-step explanation:
(A) The total number of small squares is 14, so we expect any number represented by the diagram to be a multiple of 14. If each small square represents 10 units, then the 4 small squares represent 40 units, and the rectangle represents 100 units, for a total of 140 units being represented in the diagram. Andre is correct.

(B) The above argument suggests that 410 will not be reasonably represented by the diagram. To represent 410, we expect 4 tokens that each represent 10 of a smaller token. The rectangle of 10 squares would be such a token, but the diagram has only one of those, not 4 of them. Similarly, we expect 1 of a smaller token, but the diagram has 4 of them. In any event, 410 is not a multiple of 14, so there is no (integer) value that can be assigned to a small square that lets the diagram represent 410.
I do not agree with Diego.
