• Factors of 66 - The factors of 66 are 1, 2, 3, 6, 11, 22, 33, 66
• Factors of 98 - The factors of 98 are 1, 2, 7, 14, 49, 98

The number 1997 is prime and therefore its factors are only the numbers 1 and 1997 itself. Hence, it has only one prime factor that is the number itself, i.e. 1997.

So, the prime factorization of 1997 can be written as 1997¹ where 1997 is prime.

Pair factors of 1997 are the pairs of numbers that when multiplied give the product 1997. The factors of 1997 in pairs are:

• 1 × 1997 = (1, 1997)

Negative pair factors of 1997 are:

• -1 × -1997 = (-1, -1997)

NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
