Given numbers are 298,921,698,681

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

The LCM of 298,921,698,681 is 21743386134.

Find LCM of 298,921,698,681 with Prime Factorization

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

2 x 3 x 149 x 307 x 349 x 227 = 21743386134

Therefore, the lowest common multiple of 298,921,698,681 is 21743386134.

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.

298 x 921 x 698 x 681 = 130460316804

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.

298 : 1, 2, 149, 298

921 : 1, 3, 307, 921

698 : 1, 2, 349, 698

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,921,698,681, is 1.

Now, the common factors can be found like this.

298:2x 149

921:3x 307

698:2x 349

681:3x 227

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 130460316804/(1x6)

LCM = 130460316804/6

LCM = 21743386134

Thus, we can understand that the LCM of 298,921,698,681 is 21743386134.
