Given numbers are 406,215,681,669,354

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

The LCM of 406,215,681,669,354 is 782111154930.

Find LCM of 406,215,681,669,354 with Prime Factorization

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

2 x 3 x 203 x 215 x 227 x 223 x 59 = 782111154930

Therefore, the lowest common multiple of 406,215,681,669,354 is 782111154930.

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 215 x 681 x 669 x 354 = 14078000788740

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

215 : 1, 5, 43, 215

681 : 1, 3, 227, 681

669 : 1, 3, 223, 669

354 : 1, 2, 3, 6, 59, 118, 177, 354

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,215,681,669,354, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

215:5x 43

681:3x 227

669:3x 223

354:2x 3x 59

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 14078000788740/(1x18)

LCM = 14078000788740/18

LCM = 782111154930

Thus, we can understand that the LCM of 406,215,681,669,354 is 782111154930.
