Given numbers are 398,638,620,841

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

The LCM of 398,638,620,841 is 1141388380.

Find LCM of 398,638,620,841 with Prime Factorization

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

2 x 29 x 199 x 11 x 310 x 29 = 1141388380

Therefore, the lowest common multiple of 398,638,620,841 is 1141388380.

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.

398 x 638 x 620 x 841 = 132401052080

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.

398 : 1, 2, 199, 398

638 : 1, 2, 11, 22, 29, 58, 319, 638

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,638,620,841, is 1.

Now, the common factors can be found like this.

398:2x 199

638:2x 11x 29

620:2x 2x 5x 31

841:29x 29

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 29 = 116

Therefore, the value for common factors is 116.

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 = 132401052080/(1x116)

LCM = 132401052080/116

LCM = 1141388380

Thus, we can understand that the LCM of 398,638,620,841 is 1141388380.
