Answer:
The multiplicative identity of anyinteger a is a number b which when multiplied with a, leaves it unchanged, i.e. b is called as themultiplicative identity of anyinteger a if a× b = a. Now, when we multiply 1 with any of the integersa we get a × 1 = a = 1 × a. So, 1 is the multiplicative identity forintegers.
