Given numbers are 402,487,454,389

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

The LCM of 402,487,454,389 is 17287431522.

Find LCM of 402,487,454,389 with Prime Factorization

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

2 x 201 x 487 x 227 x 389 = 17287431522

Therefore, the lowest common multiple of 402,487,454,389 is 17287431522.

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 487 x 454 x 389 = 34574863044

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

487 : 1, 487

454 : 1, 2, 227, 454

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,487,454,389, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

487:487

454:2x 227

389:389

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

2 = 2

Therefore, the value for common factors is 2.

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 = 34574863044/(1x2)

LCM = 34574863044/2

LCM = 17287431522

Thus, we can understand that the LCM of 402,487,454,389 is 17287431522.
