Given numbers are 640,368,273,575,857

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 640,368,273,575,857 is 17219529600.

Find LCM of 640,368,273,575,857 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 2 x 5 x 23 x 8 x 1 x 273 x 5 x 857 = 17219529600

Therefore, the lowest common multiple of 640,368,273,575,857 is 17219529600.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

640 x 368 x 273 x 575 x 857 = 31683934464000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

273 : 1, 3, 7, 13, 21, 39, 91, 273

575 : 1, 5, 23, 25, 115, 575

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,368,273,575,857, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

368:2x 2x 2x 2x 23

273:3x 7x 13

575:5x 5x 23

857:857

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2x 5x 23 = 1840

Therefore, the value for common factors is 1840.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 31683934464000/(1x1840)

LCM = 31683934464000/1840

LCM = 17219529600

Thus, we can understand that the LCM of 640,368,273,575,857 is 17219529600.
