Answer 1

Answer:

2

Step-by-step explanation:

           Prime factorization

2 | 72                               2 | 98

2 |36                               7 | 49

2 | 18                               7 | 7

3 | 9                                   | 1

3 | 3                                  2*7*7=98

  | 1

2*2*2*3*3=72

                 Find the common factors

common factors of 72 and 98= 2

                    The common factors of both numbers will be the ans

Hence, the common factor of both numbers, which is 2, will be the answer.
