Factoring
- ID Factors & Divisors of Numeric
Values
- Factors: numbers that multiply to equal a
number
- Ex: Factors of 90 are 9, 10, 90, 1, 30, 3, 2, 45, 18, 5, 15,
and 6
- Divisors: A number by which another number is
divided (factor=divisor)
- If you can't factor by memory alone, divide by
random numbers until you find one that
divides evenly
- Factor numeric values into
lowest terms
- Factor the number into prime
numbers
- Ex: The number 15 factors to 3
and 5, which are both prime
- Identify the GCF of numeric
values
- List all factors of the given
value.
- Ex: 81&9 Factors 81: 81, 1, 9, 27, 3 Factors 9: 3,
9, 1
- Find the largest
factor
- GCF of 81&9 is
9
