  • Prime Factorization of 10,000: 10,000 = 2 x 2 x 2 x 2 x 5 x 5 x 5 x 5 = 24 x 54

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 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000 and 10,000

Determine the least number of occurrences of 2 and 5 among the Prime Factorizations:

  • 2 occurs at least 3 times in each Prime Factorization
  • 5 occurs at least 3 times in each Prime Factorization

As a result, the Greatest Common Factor (GCF) of 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000 and 10,000 is equal to 2 x 2 x 2 x 5 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(1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, 10,000) = 23 x 53 = 2 x 2 x 2 x 5 x 5 x 5
  • GCF(1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, 10,000) = 8 x 125
  • GCF(1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, 10,000) = 1,000

Therefore, the Greatest Common Factor of 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000 and 10,000 by Prime Factorization = 1,000
