Prime factorization for 128 is 27
2^7
27 = 128
128 = 27
Prime factorization is breaking down a number into all of the prime numbers that make it up.For example, in 128, since it is even, the easiest first step would be diving by two, a prime number.64 * 2 = 128. Now divide 64, another even number, by two.32 * 2 * 2 = 128. Divide 32 by two.16 * 2 * 2 * 2 = 128. Divide by two again.8 * 2 * 2 * 2 * 2 = 128. Divide by two again.4 * 2 * 2 * 2 * 2 * 2 = 128. Divide by two a final time.2 * 2 * 2 * 2 * 2 * 2 * 2 = 128. This is your prime factorization.But you write it condensed, so 27 would be the prime factorization for 128.
The prime factorization of 128 is: 2 x 2 x 2 x 2 x 2 x 2 x 2 or 27
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
128 64,2 32,2,2 16,2,2,2 8,2,2,2,2 4,2,2,2,2,2 2,2,2,2,2,2,2
Well, honey, the greatest common factor of 128 and 224 is 16. It's like finding the biggest slice of pie they both can share without any leftovers. So, there you have it, 16 is the magic number that these two can both cozy up to.
53 is a prime number so there is no relevant prime factorization for it.
The only number with that prime factorization has to be 48.
The least common multiple (LCM) of 40, 80, and 128 is 640. To find the LCM, you can find the prime factors of each number and then take the highest power of each prime factor that appears in any of the numbers. In this case, the prime factorization of 40 is 2^3 * 5, the prime factorization of 80 is 2^4 * 5, and the prime factorization of 128 is 2^7. Taking the highest powers, we get 2^7 * 5 = 640.
