Given Numbers: 35, 65
Identify the Prime Factors of 35 and 65 by Prime Factorization
Identify the Prime Factors of 35 and 65 by Prime Factorization
- Prime Factorization of 35: 35 = 5 x 7 = 51 x 71
- Prime Factorization of 65: 65 = 5 x 13 = 51 x 131
Determine the Prime Factor(s) that are common to the Prime Factorization of each number:
- 5 is the only Prime Factor common to the Prime Factorizations of 35 and 65
Determine the least number of occurrences of 5 among the Prime Factorizations:
- 5 occurs 1 time in each Prime Factorization
As a result, the Greatest Common Factor (GCF) of 35 and 65 is equal to 5, which equals 5 raised to the power of its least number of occurrences or smallest exponent among the Prime Factorizations:
- GCF (35, 65) = 51
- GCF(35, 65) = 5
Therefore, the Greatest Common Factor of 35 and 65 by Prime Factorization = 5
