Given numbers are 402,484,638

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

The LCM of 402,484,638 is 2821236.

Find LCM of 402,484,638 with Prime Factorization

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

2 x 11 x 201 x 22 x 29 = 2821236

Therefore, the lowest common multiple of 402,484,638 is 2821236.

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 484 x 638 = 124134384

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

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,484,638, is 2.

Now, the common factors can be found like this.

402:2x 3x 67

484:2x 2x 11x 11

638:2x 11x 29

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 124134384/(2x22)

LCM = 124134384/44

LCM = 2821236

Thus, we can understand that the LCM of 402,484,638 is 2821236.
