The answer is 3. Factor out each term to get: 39 = 3 x 13 87 = 3 x 29 The GCF is 3 since that term is common for these terms. In other words, 39 and 87 have the common factor of 3.
GCF of a and b is a if b is divisible by a.87 is divisible by 29 so, GCF(29,87) = 29.
Since 39 is a factor of 78, it is automatically the GCF.
The GCF is 24.
The GCF is 13.
The GCF is 3.
The GCF of 24 and 87 is 3.
The GCF is 3.
The GCF is 3.
The factors of 39 are: 1, 3, 13, 39.The factors of 87 are: 1, 3, 29, 87.The common factors are: 1, 3.The Greatest Common Factor (GCF) is: 3
The GCF of 12, 24, and 39 is 3.The prime factorization of 12 is 2*2*3The prime factorization of 24 is 2*2*2*3The prime factorization of 39 is 3*13So the GCF of 12, 24, and 39 is 3.
The answer is 3. Factor out each term to get: 39 = 3 x 13 87 = 3 x 29 The GCF is 3 since that term is common for these terms. In other words, 39 and 87 have the common factor of 3.
