What is the GCF of 24 90 using prime factors?
It is: 2*3 which is 6
What is the greatest common factors of 18 and 24?
The GCF of 18 and 24 is 6.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The common factors are 1, 2, 3, and 6. Therefore, the greatest common factor is 6.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 18 are 2, 3, and 3.The prime factors of 24 are 2, 2, 2, and 3.The prime factors in common are 2 and 3, so the greatest common factor is 2 x 3 = 6.the GCF of 18 & 24 is... 6.
What is the greatest common factor of 72 and 16 and 24 and 64?
The GCF of 18, 24 and 64 is 2. To find the GCF of three numbers you first need to break them down into their prime factors: 18=2x3x3 24=2x2x2x3 64=2x2x2x2x2x2 The next step is to identify the common prime factors. The only prime factor which all three numbers have is 2. Therefore the GCF of 18, 24 and 64 is 2.
How do you figure greatest common factor?
To find the greatest common factor (GCF), first find the prime factorization of the two numbers. The GCF is the product of all of the prime factors the two numbers have in common. If two numbers have no common factors, the GCF is 1. (Since all numbers are divisible by 1.) Example: Find the GCF of 60 and 24. Prime factors of 60: 2, 2, 3, 5 Prime factors of 24: 2, 2, 2, 3 Common factors: 2, 2, 3 GCF: 2x2x3=12 Example: Find the GCF of 17 and 21. Prime factors of 17: 17 Prime factors of 21: 3, 7 Common factors: None (1). GCF: 1
What is the factors to find the gcf of 24 and 12?
The GCF of 24 and 12 is 12.
