Given numbers are 411,398,742,722,905

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

The LCM of 411,398,742,722,905 is 19826889431790.

Find LCM of 411,398,742,722,905 with Prime Factorization

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

2 x 411 x 199 x 371 x 361 x 905 = 19826889431790

Therefore, the lowest common multiple of 411,398,742,722,905 is 19826889431790.

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.

411 x 398 x 742 x 722 x 905 = 79307557727160

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.

411 : 1, 3, 137, 411

398 : 1, 2, 199, 398

742 : 1, 2, 7, 14, 53, 106, 371, 742

722 : 1, 2, 19, 38, 361, 722

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,398,742,722,905, is 1.

Now, the common factors can be found like this.

411:3x 137

398:2x 199

742:2x 7x 53

722:2x 19x 19

905:5x 181

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 79307557727160/(1x4)

LCM = 79307557727160/4

LCM = 19826889431790

Thus, we can understand that the LCM of 411,398,742,722,905 is 19826889431790.
