17 is the largest number that evenly divides both 102 and 85.
The number that goes into both 83 and 85 evenly is 1, as it is a common factor of all integers. However, the greatest common divisor (GCD) of 83 and 85 is also 1, since they are consecutive odd numbers and have no other common factors. Thus, the only number that divides both evenly is 1.

None!!! Because '171' is NOT an EVEN number. Remember even numbers end in 0,2,4,6,and 8. Since '171', does not end in 0,2,4,6 or 8 , then it is not an even number, so it will not divide evenly. NB However, you can divide '171' by '2' , and the answer is 85.5 or 85 1/2

NO to answer, see if 3 goes into 85 evenly. 28 x3 is 84 so the answer is no since 3 goes into 85 with a remainder of 1.

It is only possible if the denominator of the fraction, in its simplest form, is a factor of 100. In that case, find the number of times the denominator goes into 100 and then multiply the numerator of the fraction by that number. For example, suppose the given fraction is 17/20. The denominator, 20, goes into 100 five times. Therefore, multiply the numerator, 17, by 5 to give the answer as 85/100. Note that this is not possible for even simple fractions like 1/3 because 3 does not go into 100 evenly.

To convert any number to a percentage multiply it by 100% → 85 = 85 × 100% = 8500 %
The GCF is 17.
