Given numbers are 698,352,987,990

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

The LCM of 698,352,987,990 is 1818764640.

Find LCM of 698,352,987,990 with Prime Factorization

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

2 x 3 x 11 x 349 x 16 x 329 x 15 = 1818764640

Therefore, the lowest common multiple of 698,352,987,990 is 1818764640.

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.

698 x 352 x 987 x 990 = 240076932480

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.

698 : 1, 2, 349, 698

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

987 : 1, 3, 7, 21, 47, 141, 329, 987

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,352,987,990, is 1.

Now, the common factors can be found like this.

698:2x 349

352:2x 2x 2x 2x 2x 11

987:3x 7x 47

990:2x 3x 3x 5x 11

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 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 240076932480/(1x132)

LCM = 240076932480/132

LCM = 1818764640

Thus, we can understand that the LCM of 698,352,987,990 is 1818764640.
