I assume you mean 8.2x102 and not 102, and same with the 105. This will be 1.722x108
102 * 21 = 2,142
105 - 21 = 84
Since 21 is a factor of 105, it is automatically the GCF.
105° set in 1936 and tied on July 31, 1999. 105° was recorded at the Toledo Airport on July 21 2011, but that is not the official measuring station so it did not tie the record high in Toledo. Officially it was 102° on July 21 in Toledo.

5
One-fifth of 105 is calculated by dividing 105 by 5. This equals 21. Therefore, one-fifth of 105 is 21.
4.8571
5 x 21 = 105
Since 21 is a factor of 105, it is automatically the GCF.
21 = 105/5
The average is 35. (21 + 35 + 49 (=105), divided by 3.)
