Given numbers are 998,360,780,681

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

The LCM of 998,360,780,681 is 530117640.

Find LCM of 998,360,780,681 with Prime Factorization

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

2 x 2 x 3 x 5 x 499 x 6 x 13 x 227 = 530117640

Therefore, the lowest common multiple of 998,360,780,681 is 530117640.

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.

998 x 360 x 780 x 681 = 190842350400

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.

998 : 1, 2, 499, 998

360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,360,780,681, is 1.

Now, the common factors can be found like this.

998:2x 499

360:2x 2x 2x 3x 3x 5

780:2x 2x 3x 5x 13

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 2x 2x 3x 3x 5 = 360

Therefore, the value for common factors is 360.

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 = 190842350400/(1x360)

LCM = 190842350400/360

LCM = 530117640

Thus, we can understand that the LCM of 998,360,780,681 is 530117640.
