Given numbers are 840,368,578,172,662

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

The LCM of 840,368,578,172,662 is 158939341680.

Find LCM of 840,368,578,172,662 with Prime Factorization

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

2 x 2 x 2 x 105 x 46 x 289 x 43 x 331 = 158939341680

Therefore, the lowest common multiple of 840,368,578,172,662 is 158939341680.

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.

840 x 368 x 578 x 172 x 662 = 20344235735040

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

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

578 : 1, 2, 17, 34, 289, 578

172 : 1, 2, 4, 43, 86, 172

662 : 1, 2, 331, 662

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,368,578,172,662, is 2.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

368:2x 2x 2x 2x 23

578:2x 17x 17

172:2x 2x 43

662:2x 331

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 2 = 64

Therefore, the value for common factors is 64.

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 = 20344235735040/(2x64)

LCM = 20344235735040/128

LCM = 158939341680

Thus, we can understand that the LCM of 840,368,578,172,662 is 158939341680.
