Given numbers are 854,321,447,915

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

The LCM of 854,321,447,915 is 204229830.

Find LCM of 854,321,447,915 with Prime Factorization

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

3 x 61 x 14 x 107 x 149 x 5 = 204229830

Therefore, the lowest common multiple of 854,321,447,915 is 204229830.

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.

854 x 321 x 447 x 915 = 112122176670

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.

854 : 1, 2, 7, 14, 61, 122, 427, 854

321 : 1, 3, 107, 321

447 : 1, 3, 149, 447

915 : 1, 3, 5, 15, 61, 183, 305, 915

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,321,447,915, is 1.

Now, the common factors can be found like this.

854:2x 7x 61

321:3x 107

447:3x 149

915:3x 5x 61

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

3x 3x 61 = 549

Therefore, the value for common factors is 549.

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 = 112122176670/(1x549)

LCM = 112122176670/549

LCM = 204229830

Thus, we can understand that the LCM of 854,321,447,915 is 204229830.
