Given Numbers: 650, 4,500
Identify the Prime Factors of 650 and 4,500 by Prime Factorization
Identify the Prime Factors of 650 and 4,500 by Prime Factorization
- Prime Factorization of 650: 650 = 2 x 5 x 5 x 13 = 21 x 52 x 131
- Prime Factorization of 4,500: 4,500 = 2 x 2 x 3 x 3 x 5 x 5 x 5 = 22 x 32 x 53
Determine the Prime Factor(s) that are common to the Prime Factorization of each number:
- 2 and 5 are Prime Factors common to the Prime Factorizations of 650 and 4,500
Determine the least number of occurrences of 2 and 5 among the Prime Factorizations:
- 2 occurs at least 1 time in each Prime Factorization
- 5 occurs at least 2 times in each Prime Factorization
As a result, the Greatest Common Factor (GCF) of 650 and 4,500 is equal to 2 x 5 x 5, which equals the product of 2 and 5 raised to the powers of their least number of occurrences or smallest exponent among the Prime Factorizations:
- GCF(650, 4,500) = 21 x 52 = 2 x 5 x 5
- GCF(650, 4,500) = 2 x 25
- GCF(650, 4,500) = 50
Therefore, the Greatest Common Factor of 650 and 4,500 by Prime Factorization = 50
