Given numbers are 765,320,257,994,609

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

The LCM of 765,320,257,994,609 is 181354743360.

Find LCM of 765,320,257,994,609 with Prime Factorization

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

2 x 3 x 5 x 7 x 51 x 32 x 257 x 71 x 29 = 181354743360

Therefore, the lowest common multiple of 765,320,257,994,609 is 181354743360.

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.

765 x 320 x 257 x 994 x 609 = 38084496105600

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.

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

257 : 1, 257

994 : 1, 2, 7, 14, 71, 142, 497, 994

609 : 1, 3, 7, 21, 29, 87, 203, 609

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,320,257,994,609, is 1.

Now, the common factors can be found like this.

765:3x 3x 5x 17

320:2x 2x 2x 2x 2x 2x 5

257:257

994:2x 7x 71

609:3x 7x 29

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

2x 3x 5x 7 = 210

Therefore, the value for common factors is 210.

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 = 38084496105600/(1x210)

LCM = 38084496105600/210

LCM = 181354743360

Thus, we can understand that the LCM of 765,320,257,994,609 is 181354743360.
