Given numbers are 780,334,489,391

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

The LCM of 780,334,489,391 is 8301860580.

Find LCM of 780,334,489,391 with Prime Factorization

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

2 x 3 x 130 x 167 x 163 x 391 = 8301860580

Therefore, the lowest common multiple of 780,334,489,391 is 8301860580.

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.

780 x 334 x 489 x 391 = 49811163480

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

334 : 1, 2, 167, 334

489 : 1, 3, 163, 489

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,334,489,391, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

334:2x 167

489:3x 163

391:17x 23

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 49811163480/(1x6)

LCM = 49811163480/6

LCM = 8301860580

Thus, we can understand that the LCM of 780,334,489,391 is 8301860580.
