What is the prime factorization of 71421 use the prime factors what is the LCM and GCF of each number?
The prime factorization of 71421 is 3 x 7 x 19 x 179 but that's probably not what we're dealing with here. 7 2 x 7 = 14 3 x 7 = 21 The LCM and GCF refer to the set as a whole, not the individual numbers. The GCF of 7, 14, 21 is 7 The LCM of 7, 14, 21 is 42
Prime factorization of 294?
14*21
What is the greatest common factor of 21 35 and 81?
The GCF of 21, 35, and 81 is 1. The prime factorization of 21 is 3*7 The prime factorization of 35 is 5*7 The prime factorization of 81 is 3*3*3*3 So they have no common factor other than 1, which is the GCF.
What are the prime factorization and the greatest common factor of 21 and 56?
The prime factorization of 21 is 3 x 7 = 21The prime factorization of 56 is 2 x 2 x 2 x 7 = 56The GCF of 21 and 56 is 7.
What is the prime factorization of 14 using exponets?
It is: 21*71 = 14
What is the prime factorization of 14 using exponents?
14 = 21 x 71
What is the greatest common factor of 6 15 and 21?
The greatest common factor of 6, 15 and 21 is 3. The prime factorization of 6 is 2*3 The prime factorization of 15 is 3*5 The prime factorization of 21 is 3*7 The GCF is then 3, as it is the only common factor.
What is the greatest common factor of 18 and 21?
The GCF of 18 and 21 is 3.The prime factorization of 18 is 2*3*3The prime factorization of 21 is 3*7So the GCF of 18 and 21 is 3.You can also notice that the difference between 21 and 18 is 3. The GCF can be no larger than the difference between the numbers. Since 3 is a factor of both 18 and 21, it is the GCF.The GCF is 3.3
What is the GCF of 14m and 21m?
GCF(28, 21) = 7 Steps: Prime factorization of the numbers: 28 = 2 × 2 × 7 21 = 3 × 7 GCF(28, 21) = 7
What is the prime factorization for 21?
The prime factorization for 21 is: 3x73 x 7 = 21
What is the greatest common factor of 63 84 and 105?
The GCF of 63, 84, and 105 = 21 The prime factorization of 63 = 3^2 x 7 The prime factorization of 84 = 2^2 x 3 x 7 The prime factorization of 105 = 3 x 5 x 7 The GCF is the product of the lowest power of the primes common to all number factorizations, so the gcf = 3 x 7 = 21
What is the gcf of 14 21 and 8?
1. These numbers are co-prime
