Given numbers are 387,321,817,109

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

The LCM of 387,321,817,109 is 85758039.

Find LCM of 387,321,817,109 with Prime Factorization

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

3 x 43 x 3 x 107 x 19 x 109 = 85758039

Therefore, the lowest common multiple of 387,321,817,109 is 85758039.

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.

387 x 321 x 817 x 109 = 11062787031

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.

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

321 : 1, 3, 107, 321

817 : 1, 19, 43, 817

109 : 1, 109

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,321,817,109, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

321:3x 107

817:19x 43

109:109

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 = 11062787031/(1x129)

LCM = 11062787031/129

LCM = 85758039

Thus, we can understand that the LCM of 387,321,817,109 is 85758039.
