Given numbers are 815,478,338,102

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

The LCM of 815,478,338,102 is 3357703830.

Find LCM of 815,478,338,102 with Prime Factorization

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

2 x 815 x 239 x 169 x 51 = 3357703830

Therefore, the lowest common multiple of 815,478,338,102 is 3357703830.

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.

815 x 478 x 338 x 102 = 13430815320

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.

815 : 1, 5, 163, 815

478 : 1, 2, 239, 478

338 : 1, 2, 13, 26, 169, 338

102 : 1, 2, 3, 6, 17, 34, 51, 102

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,478,338,102, is 1.

Now, the common factors can be found like this.

815:5x 163

478:2x 239

338:2x 13x 13

102:2x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 13430815320/(1x4)

LCM = 13430815320/4

LCM = 3357703830

Thus, we can understand that the LCM of 815,478,338,102 is 3357703830.
