GCF of 16 and 32
GCF of 16 and 32
The greatest common factor (GCF) of 16 and 32 is 16. Both 16 and 32 share 16 as their largest common divisors. By prime factorizing 16 and 32, it’s evident that they both have 2 as a common factor, and 16 has an additional factor of 2. Thus, the GCF is determined by the common factors with the lowest power, which is 2 raised to the power of 4, resulting in 16. Therefore, 16 is the largest integer that divides both 16 and 32 without leaving a remainder, making it the greatest common factor.
GCF of 16 and 32
GCF of 16 and 32 is 16.
GCF of 16 and 32 by Prime Factorization Method.
To find the greatest common factor (GCF) of 16 and 32 using the prime factorization method:
Step 1: Prime factorize both numbers:
For 16: 16 = 2⁴
For 32: 32 = 2⁵
Step 2: Identify the common prime factors and their lowest powers:
- Both 16 and 32 have the common prime factor of 2. The lowest power common to both is 2⁴.
Step 3: Multiply the common prime factors with their lowest powers:
GCF = 2⁴ = 16
Therefore, the greatest common factor (GCF) of 16 and 32 by prime factorization method is 16.
GCF of 16 and 32 by Long Division Method.
To find the greatest common factor (GCF) of 16 and 32 using the long division method:
Step 1: Start by dividing the larger number (32) by the smaller number (16).
32 ÷ 16 = 2 with a remainder of 0.
Since there is no remainder, the division process stops here.
Step 2: The divisor at this step, where the remainder becomes zero, is the greatest common factor.
GCF = 16.
Therefore, the greatest common factor (GCF) of 16 and 32 by the long division method is 16.
GCF of 16 and 32 by Listing Common Factors.
To find the greatest common factor (GCF) of 16 and 32 by listing common factors:
Step 1: List the factors of each number.
Factors of 16: 1, 2, 4, 8, 16
Factors of 32: 1, 2, 4, 8, 16, 32
Step 2: Identify the common factors.
Common factors: 1, 2, 4, 8, 16
Step 3: Determine the greatest common factor. GCF =16.
Therefore, the greatest common factor (GCF) of 16 and 32 by listing common factors is 16.
