Given numbers are 774,347,181,406,408

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

The LCM of 774,347,181,406,408 is 671048578872.

Find LCM of 774,347,181,406,408 with Prime Factorization

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

2 x 3 x 129 x 347 x 181 x 203 x 68 = 671048578872

Therefore, the lowest common multiple of 774,347,181,406,408 is 671048578872.

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.

774 x 347 x 181 x 406 x 408 = 8052582946464

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

347 : 1, 347

181 : 1, 181

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

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,347,181,406,408, is 1.

Now, the common factors can be found like this.

774:2x 3x 3x 43

347:347

181:181

406:2x 7x 29

408:2x 2x 2x 3x 17

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 3 = 12

Therefore, the value for common factors is 12.

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 = 8052582946464/(1x12)

LCM = 8052582946464/12

LCM = 671048578872

Thus, we can understand that the LCM of 774,347,181,406,408 is 671048578872.
