Given numbers are 640,540,346,246,816

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

The LCM of 640,540,346,246,816 is 2083639680.

Find LCM of 640,540,346,246,816 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 5 x 8 x 9 x 173 x 41 x 17 = 2083639680

Therefore, the lowest common multiple of 640,540,346,246,816 is 2083639680.

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 540 x 346 x 246 x 816 = 24003529113600

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

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

346 : 1, 2, 173, 346

246 : 1, 2, 3, 6, 41, 82, 123, 246

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,540,346,246,816, is 2.

Now, the common factors can be found like this.

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

540:2x 2x 3x 3x 3x 5

346:2x 173

246:2x 3x 41

816:2x 2x 2x 2x 3x 17

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 2x 2x 2x 3x 3x 5 = 5760

Therefore, the value for common factors is 5760.

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 = 24003529113600/(2x5760)

LCM = 24003529113600/11520

LCM = 2083639680

Thus, we can understand that the LCM of 640,540,346,246,816 is 2083639680.
