To find the greatest number of students that can be in each row, we need to find the greatest common divisor (GCD) of 35 and 21.
The prime factorization of 35 is 5 * 7.
The prime factorization of 21 is 3 * 7.
The common prime factors are 7, so the GCD of 35 and 21 is 7.
Therefore, the greatest number of students that can be in each row is 7.
