Given numbers are 406,138,997,910,806

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

The LCM of 406,138,997,910,806 is 56278865370.

Find LCM of 406,138,997,910,806 with Prime Factorization

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

2 x 7 x 13 x 29 x 69 x 997 x 5 x 31 = 56278865370

Therefore, the lowest common multiple of 406,138,997,910,806 is 56278865370.

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 138 x 997 x 910 x 806 = 40971013989360

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

997 : 1, 997

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

806 : 1, 2, 13, 26, 31, 62, 403, 806

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,138,997,910,806, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

138:2x 3x 23

997:997

910:2x 5x 7x 13

806:2x 13x 31

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 2x 7x 13 = 728

Therefore, the value for common factors is 728.

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 = 40971013989360/(1x728)

LCM = 40971013989360/728

LCM = 56278865370

Thus, we can understand that the LCM of 406,138,997,910,806 is 56278865370.
