Given numbers are 402,338,813,789

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

The LCM of 402,338,813,789 is 4842145074.

Find LCM of 402,338,813,789 with Prime Factorization

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

2 x 3 x 67 x 169 x 271 x 263 = 4842145074

Therefore, the lowest common multiple of 402,338,813,789 is 4842145074.

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.

402 x 338 x 813 x 789 = 87158611332

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

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

813 : 1, 3, 271, 813

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,338,813,789, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

338:2x 13x 13

813:3x 271

789:3x 263

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 87158611332/(1x18)

LCM = 87158611332/18

LCM = 4842145074

Thus, we can understand that the LCM of 402,338,813,789 is 4842145074.
