Given numbers are 406,521,893,782

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

The LCM of 406,521,893,782 is 73857052738.

Find LCM of 406,521,893,782 with Prime Factorization

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

2 x 203 x 521 x 893 x 391 = 73857052738

Therefore, the lowest common multiple of 406,521,893,782 is 73857052738.

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.

406 x 521 x 893 x 782 = 147714105476

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

521 : 1, 521

893 : 1, 19, 47, 893

782 : 1, 2, 17, 23, 34, 46, 391, 782

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,521,893,782, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

521:521

893:19x 47

782:2x 17x 23

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 = 147714105476/(1x2)

LCM = 147714105476/2

LCM = 73857052738

Thus, we can understand that the LCM of 406,521,893,782 is 73857052738.
