Given numbers are 642,488,698,598,165

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

The LCM of 642,488,698,598,165 is 899050649640.

Find LCM of 642,488,698,598,165 with Prime Factorization

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

2 x 3 x 107 x 244 x 349 x 299 x 55 = 899050649640

Therefore, the lowest common multiple of 642,488,698,598,165 is 899050649640.

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.

642 x 488 x 698 x 598 x 165 = 21577215591360

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

488 : 1, 2, 4, 8, 61, 122, 244, 488

698 : 1, 2, 349, 698

598 : 1, 2, 13, 23, 26, 46, 299, 598

165 : 1, 3, 5, 11, 15, 33, 55, 165

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,488,698,598,165, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

488:2x 2x 2x 61

698:2x 349

598:2x 13x 23

165:3x 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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 21577215591360/(1x24)

LCM = 21577215591360/24

LCM = 899050649640

Thus, we can understand that the LCM of 642,488,698,598,165 is 899050649640.
