Step-by-step solution to find the factors and factor pairs of 155:
- If a whole number divides 155 evenly (remainder = 0), then it is a factor of 155 (divisor factor), and the corresponding quotient is also a factor of 155 (quotient factor)
- Divisor factors and quotient factors form a complete list of the factors and factor pairs of 155
- With the exception of 0, all whole numbers less than or equal to the square root of 155 (√155 ) are possible divisor factors of 155
- √155 = 12.4499
- Possible Divisor Factors of 155: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
- Filter list of possible divisor factors by testing divisibility of 155 by 2, 3, 4, 5, 9, and 10
- Possible Divisor Factors of 155 (filtered): 1, 5, 7, 11
- Divide 155 by the possible divisor factors in the filtered list
- Factors of 155: 1, 5, 31, 155
- Factor Pairs of 155: (1*155) (5*31)
- Note: the first number in each factor pair is a divisor factor and the second number is a corresponding quotient factor
