Greatest Common Factor of 24, 48 and 96 by Prime Factorization

Given Numbers: 24, 48, 96
Identify the Prime Factors of 24, 48 and 96 by Prime Factorization

• Prime Factorization of 24: 24 = 2 x 2 x 2 x 3 = 2³ x 3¹
• Prime Factorization of 48: 48 = 2 x 2 x 2 x 2 x 3 = 2⁴ x 3¹
• Prime Factorization of 96: 96 = 2 x 2 x 2 x 2 x 2 x 3 = 2⁵ x 3¹

Determine the Prime Factor(s) that are common to the Prime Factorization of each number:

• 2 and 3 are Prime Factors common to the Prime Factorizations of 24, 48 and 96

Determine the least number of occurrences of 2 and 3 among the Prime Factorizations:

• 2 occurs at least 3 times in each Prime Factorization
• 3 occurs 1 time in each Prime Factorization

As a result, the Greatest Common Factor (GCF) of 24, 48 and 96 is equal to 2 x 2 x 2 x 3, which equals the product of 2 and 3 raised to the powers of their least number of occurrences or smallest exponent among the Prime Factorizations:

• GCF(24, 48, 96) = 2³ x 3¹ = 2 x 2 x 2 x 3
• GCF(24, 48, 96) = 8 x 3
• GCF(24, 48, 96) = 24

Therefore, the Greatest Common Factor of 24, 48 and 96 by Prime Factorization = 24
