Given numbers are 400,682,638,539

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

The LCM of 400,682,638,539 is 193824400.

Find LCM of 400,682,638,539 with Prime Factorization

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

2 x 11 x 200 x 31 x 29 x 49 = 193824400

Therefore, the lowest common multiple of 400,682,638,539 is 193824400.

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.

400 x 682 x 638 x 539 = 93811009600

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.

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

682 : 1, 2, 11, 22, 31, 62, 341, 682

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

539 : 1, 7, 11, 49, 77, 539

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,682,638,539, is 1.

Now, the common factors can be found like this.

400:2x 2x 2x 2x 5x 5

682:2x 11x 31

638:2x 11x 29

539:7x 7x 11

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 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 93811009600/(1x484)

LCM = 93811009600/484

LCM = 193824400

Thus, we can understand that the LCM of 400,682,638,539 is 193824400.
