Given numbers are 306,638,654,915

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

The LCM of 306,638,654,915 is 3245177430.

Find LCM of 306,638,654,915 with Prime Factorization

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

2 x 3 x 51 x 319 x 109 x 305 = 3245177430

Therefore, the lowest common multiple of 306,638,654,915 is 3245177430.

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.

306 x 638 x 654 x 915 = 116826387480

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.

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

638 : 1, 2, 11, 22, 29, 58, 319, 638

654 : 1, 2, 3, 6, 109, 218, 327, 654

915 : 1, 3, 5, 15, 61, 183, 305, 915

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,638,654,915, is 1.

Now, the common factors can be found like this.

306:2x 3x 3x 17

638:2x 11x 29

654:2x 3x 109

915:3x 5x 61

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 3 = 36

Therefore, the value for common factors is 36.

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 = 116826387480/(1x36)

LCM = 116826387480/36

LCM = 3245177430

Thus, we can understand that the LCM of 306,638,654,915 is 3245177430.
