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.

What is the least common multiple of 40 80 and 128?

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.

How do you find the prime numbers of 640?

This one is very easy. You can see at once that 640 is an even number. So, write down 2, then divide 640 by 2. 320 is also even; write down another 2, divide 320 by 2. 160 is also even; etc, etc. At the end you will find 7 2s have been written, and the result of the last divide was 5. 5 is a prime number so the prime factors of 640 are 2 2 2 2 2 2 2 5.
