Given numbers are 402,807,381,454

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

The LCM of 402,807,381,454 is 3117510402.

Find LCM of 402,807,381,454 with Prime Factorization

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

2 x 3 x 67 x 269 x 127 x 227 = 3117510402

Therefore, the lowest common multiple of 402,807,381,454 is 3117510402.

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 807 x 381 x 454 = 56115187236

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

807 : 1, 3, 269, 807

381 : 1, 3, 127, 381

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,807,381,454, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

807:3x 269

381:3x 127

454:2x 227

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 = 56115187236/(1x18)

LCM = 56115187236/18

LCM = 3117510402

Thus, we can understand that the LCM of 402,807,381,454 is 3117510402.
