What is the GCF of 20 28 36?
The factors of 28 are:1, 2, 4, 7, 14, 28The factors of 78 are:1, 2, 3, 6, 13, 26, 39, 78The common factors are:1, 2The Greatest Common Factor (GCF) is: 2
What is the gcf pf 20 and 28?
The GCF of 20 and 28 is 4
What is the highest common factor of 28 32?
To find the highest common factor of two numbers, you must first split them into their prime factors. In this case, the numbers 28 and 32 can split as follows: 28 = 2x2x7 32 = 2x2x2x2x2 The next step is to identify all common prime factors. In this case, the common prime factors are two 2s. To find the HCF, you just multiply these together: 2x2=4 Thus the highest common factor of 28 and 32 is 4.

The factors of 80 are:1, 2, 4, 5, 8, 10, 16, 20, 40, 80The factors of 140 are:1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140The common factors are:1, 2, 4, 5, 10, 20The Greatest Common Factor (GCF) is:20
What is the greatest common factor of 28 and 20?
The Greatest Common Factor (GCF) of 20 and 28 is 4.The factors of 20 are 1, 2, 4, 5, 10, and 20The factors of 28 are 1, 2, 4, 7, 14, and 28The common factors are: 1, 2, 4The Greatest Common Factor (GCF) is: 4
What is the GCF of 28 20 and 40?
To find the GCF, you first need to break the numbers down into their prime factors: 28 = 2x2x7 20 = 2x2x5 40 = 2x2x2x5 The next step is to find any common prime factors. In this case, all three numbers have two 2s as prime factors. Multiply these and you get 4. Therefore the GCF of 28, 20 and 40 is 4.
What is the GCF of 20 28 36?
The factors of 28 are:1, 2, 4, 7, 14, 28The factors of 78 are:1, 2, 3, 6, 13, 26, 39, 78The common factors are:1, 2The Greatest Common Factor (GCF) is: 2
What is the gcf of 28 12 and 20?
To calculate the GCF you first have to split the numbers into their prime factors: 28 = 2x2x7 12 = 2x2x3 20 = 2x2x5 The next step is to identify any common factors. In this case, all three numbers have two 2s. Multiply these together and you get 4. Therefore the GCF of 28, 12 and 20 is 4.
What is the highest common factor of 28 32?
To find the highest common factor of two numbers, you must first split them into their prime factors.
