2x2 (i.e. 4)
how
The greatest common factor of 12, 28, and 40 is 4 To find the greatest common factor of numbers, you first need to split these numbers into their prime factors: 12 = 2x2x3 28 = 2x2x7 40 = 2x2x2x2x5 You then need to find which prime factors are shared between the numbers. In this case, each of the numbers uses two 2s, but no other numbers are common between them. So to find the GCF we simply multiply two 2s: 2x2=4 Thus the GCF of 12, 28 and 40 is 4.
The greatest common of 4 and 34 is 2.Factors for 4 = 1x4, 2x2 = 1,2,4Factors for 34 = 1x34, 2x17 = 1,2,17,34Therefore, the GCF is.............(drumroll, please).............2 !
You would first factor out anything that is common between the 3 parts. 2x2 is the greatest common factor. To pull out the 2x2, you divide each term by 2x2 like so:12x4/2x2=6x210x3/2x2=5x-12x2/2x2=-6We now know that 12x4+10x3-12x2= 2x2(6x2+5x-6)The next step involves using the "slip and slide" method for the trinomial inside the parentheses:6x2+5x-6x2+5x-36(x+9)(x-4)(x+9/6)(x-4/6)(x+3/2)(x-2/3)(2x+3)(3x-2)Remembering that the result for the slip and slide method only accounts for 6x2+5x-6 we must multiply (2x+3)(3x-2) by 2x2.Your final answer is 2x2(2x+3)(3x-2).
(2x2 - 1)(2x2 - 1) or (2x2 - 1)2

Show the terms as additive here..., 8X2 + 10X3 factor out 2X2 2X2(4 + 5X) ---------------- 2X2 ==== greatest common factor
2 x 2
2x2x3=12 so therefore 12=2x2x3 2x2=4x3=12
The GCF of 4 and 12 is 4.
12 = 2x2x3 20 = 2x2x5 the both have 2x2 in common = 4
Answer: 4Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 12 are 1, 2, 3, 4, 6, and 12.The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.
The greatest common factor of 12, 28, and 40 is 4 To find the greatest common factor of numbers, you first need to split these numbers into their prime factors: 12 = 2x2x3 28 = 2x2x7 40 = 2x2x2x2x5 You then need to find which prime factors are shared between the numbers. In this case, each of the numbers uses two 2s, but no other numbers are common between them. So to find the GCF we simply multiply two 2s: 2x2=4 Thus the GCF of 12, 28 and 40 is 4.
2: 2x2=4 , 4x2=8, 12x2=24
GCF comes from more than one term. To do that you need to prime factor each of the numbers and then multiply all the factors that are common. Let's do 12 and16. 12=2x2x3 16=2x2x2x2 Common factors are 2x2=4
To find the greatest common factor and lowest common multiple of two numbers, you first need to split those numbers up into their prime factors. In this case: 8 = 2x2x2 12 = 2x2x3 The next step is to identify any common factors. In this case the common factors are two 2s. To find the greatest common factor, you multiply these together: 2x2 = 4. A quick way to find the lowest common multiple is to multiply the two original numbers together and divide by the greatest common factor. So 8x12/4 = 24. Thus 24 is the lowest common multiple.
If you are talking of 20 and 24 then factor both to prime factors. 20=2x2x5 24=2x2x2x3 circle the common ones. 2x2=4 the greatest common factor.
