To find the Greatest Common Factor (GCF) of 24, 40, and 48, we first need to find the prime factorization of each number. The prime factorization of 24 is 2^3 * 3, the prime factorization of 40 is 2^3 * 5, and the prime factorization of 48 is 2^4 * 3. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^3 = 8. Therefore, the GCF of 24, 40, and 48 is 8.
The GCF of 35 and 40 is 5. The prime factorization of 35 is 5*7. The prime factorization of 40 is 2*2*2*5 The GCF is 5, which is the only common factor.
The GCF of 20 and 66 is 2. The prime factorization of 20 is 2*2*2 The prime factorization of 66 is 2*3*11 Their only common factor is 2, so it is their GCF.
The GCF of 40 and 224 is 8 The prime factorization of 40 is 2*2*2*5. The prime factorization of 224 is 2*2*2*2*2*7 The GCF of 2*2*2 = 8.
Method of prime factorization is one of the best method to find out greatest common factor.Prime factorization of 32 = 2x2x2x2x2Prime factorization of 8 = 2x2x2Prime factorization of 40 = 2x2x2x52x2x2 is a factor of each number. Also, it is the greatest number which divides 32, 8 and 40. So, gcf is 8.See the related links below to know more about prime factorization.
In 32 40,Use prime factorization to find the GCF of each pair
The gcf is the greatest common factor. A way of finding the gcf of three numbers is to find the gcf of the first two and then finding the gcf of that number and the third number. Because of the unique prime factorization theorem, the greatest common factor will be a product of some of the prime factors in either number. The prime factorization of 40 is 2^3 * 5 and the prime factorization of 60 is 2^2 * 3 * 5, so the gcf is going to be what is in both, or, in this case, 2^2 * 5. Th prime factorization of 80 is 2^4 * 5 and so gcf of all three numbers is 2^2 * 5, or 20.
Prime factorization of 40 = 2x2x2x5 Prime factorization of 100 = 2x2x5x5
The GCF is 20. Prime Factorization of: 40 = 2 * 2 * 2 * 5 60 = 2 * 2 ..... * 5 * 3 ================ GCF=2 * 2 .....* 5 GCF=20
Factors of 6 are 1, 2, 3 and 6.Factors of 40 are 1, 2, 4, 5, 8, 10, 20 and 40.Common factors are 1 and 2. Therefore, the greatest common factors(gcf) is 2.Alternate method:The method used above is not useful for finding GCF of larger numbers.However, the method of prime factorization is very useful and simple for finding GCF.Prime factorization of 6 = 2x3Prime factorization of 40 = 2x2x2x5It is clear from the factorization of both numbers that 2 is the GCF.
