The prime factors of 640 are 2, 2, 2, 2, 2, 2, 2, and 5. The prime factors of 412 are 2, 2, and 103. The factors they have in common are two 2s, so 2 x 2 = 4 is the greatest common factor.
The common multiples of 16 and 20 are 80, 160, 240, 320, 400, 480, 560, 640, and so on.
Answer: Infinity or there is none.One common multiple of 16 and 20 is 320. If you double it, which is 640, you have a larger common multiple. If you double it again, which is 1320, you have an even larger common multiple. You can continue doubling it forever, so there is no greatest common multiple, or it can be said to be infinite.The greatest common multiple of any set of numbers is infinite.
640 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 16 factors of 640 are 1 2 4 5 8 10 16 20 32 40 64 80 128 160 320 640.The prime factors of 640 are 2, 2, 2, 2, 2, 2, 2, and 5.Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The 2 distinct prime factors (listing each prime factor only once) of 640 are 2 and 5.The prime factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 or, in index form (in other words, using exponents), 27 x 5.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
640: Prime factorization: (2^7)(5) Every factor: 1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640
The GCF is 320.
The GCF is 20.
The greatest common factor (GCF) of 640 and 256 is 128.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 528 and 4840 is 88
I'm not sure what you mean by lowest common factor, typically math teacher will ask for least common multiple or greatest common factor on your homework.While the lowest common factor is 1, 1 is also the greatest common factor. The least common multiple is 640.
The prime factors of 640 are 2, 2, 2, 2, 2, 2, 2, and 5. The prime factors of 412 are 2, 2, and 103. The factors they have in common are two 2s, so 2 x 2 = 4 is the greatest common factor.
Well, isn't that a happy little question? Let's find the greatest common factor of 256 and 640. We can start by listing the factors of each number and then finding the largest number they have in common. It looks like the greatest common factor of 256 and 640 is 128. Just like painting, math can be a joyful experience when we break it down into simple steps.
It is 480.
75% of 640= 75% * 640= 0.75 * 640= 480
