Given numbers are 402,781,260,324

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

The LCM of 402,781,260,324 is 1102006620.

Find LCM of 402,781,260,324 with Prime Factorization

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

2 x 2 x 3 x 67 x 781 x 65 x 27 = 1102006620

Therefore, the lowest common multiple of 402,781,260,324 is 1102006620.

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 781 x 260 x 324 = 26448158880

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

781 : 1, 11, 71, 781

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,781,260,324, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

781:11x 71

260:2x 2x 5x 13

324:2x 2x 3x 3x 3x 3

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

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 26448158880/(1x24)

LCM = 26448158880/24

LCM = 1102006620

Thus, we can understand that the LCM of 402,781,260,324 is 1102006620.
