Given numbers are 305,397,878,408,551

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

The LCM of 305,397,878,408,551 is 11949964862520.

Find LCM of 305,397,878,408,551 with Prime Factorization

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

2 x 305 x 397 x 439 x 204 x 551 = 11949964862520

Therefore, the lowest common multiple of 305,397,878,408,551 is 11949964862520.

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.

305 x 397 x 878 x 408 x 551 = 23899929725040

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.

305 : 1, 5, 61, 305

397 : 1, 397

878 : 1, 2, 439, 878

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,397,878,408,551, is 1.

Now, the common factors can be found like this.

305:5x 61

397:397

878:2x 439

408:2x 2x 2x 3x 17

551:19x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 23899929725040/(1x2)

LCM = 23899929725040/2

LCM = 11949964862520

Thus, we can understand that the LCM of 305,397,878,408,551 is 11949964862520.
