Given numbers are 817,867,623,387

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

The LCM of 817,867,623,387 is 1323885591.

Find LCM of 817,867,623,387 with Prime Factorization

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

3 x 43 x 19 x 289 x 623 x 3 = 1323885591

Therefore, the lowest common multiple of 817,867,623,387 is 1323885591.

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.

817 x 867 x 623 x 387 = 170781241239

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.

817 : 1, 19, 43, 817

867 : 1, 3, 17, 51, 289, 867

623 : 1, 7, 89, 623

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,867,623,387, is 1.

Now, the common factors can be found like this.

817:19x 43

867:3x 17x 17

623:7x 89

387:3x 3x 43

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

3x 43 = 129

Therefore, the value for common factors is 129.

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 = 170781241239/(1x129)

LCM = 170781241239/129

LCM = 1323885591

Thus, we can understand that the LCM of 817,867,623,387 is 1323885591.
