Given numbers are 402,492,473,489

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

The LCM of 402,492,473,489 is 2541491436.

Find LCM of 402,492,473,489 with Prime Factorization

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

2 x 3 x 67 x 82 x 473 x 163 = 2541491436

Therefore, the lowest common multiple of 402,492,473,489 is 2541491436.

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 492 x 473 x 489 = 45746845848

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

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

473 : 1, 11, 43, 473

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,492,473,489, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

492:2x 2x 3x 41

473:11x 43

489:3x 163

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 = 45746845848/(1x18)

LCM = 45746845848/18

LCM = 2541491436

Thus, we can understand that the LCM of 402,492,473,489 is 2541491436.
