Given numbers are 802,221,642,173,560

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

The LCM of 802,221,642,173,560 is 2755978396080.

Find LCM of 802,221,642,173,560 with Prime Factorization

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

2 x 401 x 221 x 321 x 173 x 280 = 2755978396080

Therefore, the lowest common multiple of 802,221,642,173,560 is 2755978396080.

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.

802 x 221 x 642 x 173 x 560 = 11023913584320

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.

802 : 1, 2, 401, 802

221 : 1, 13, 17, 221

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

173 : 1, 173

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,221,642,173,560, is 1.

Now, the common factors can be found like this.

802:2x 401

221:13x 17

642:2x 3x 107

173:173

560:2x 2x 2x 2x 5x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 11023913584320/(1x4)

LCM = 11023913584320/4

LCM = 2755978396080

Thus, we can understand that the LCM of 802,221,642,173,560 is 2755978396080.
