Given numbers are 181,637,280,728,397

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

The LCM of 181,637,280,728,397 is 1830916360.

Find LCM of 181,637,280,728,397 with Prime Factorization

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

2 x 2 x 2 x 7 x 13 x 181 x 1 x 5 x 7 x 397 = 1830916360

Therefore, the lowest common multiple of 181,637,280,728,397 is 1830916360.

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.

181 x 637 x 280 x 728 x 397 = 9330349770560

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.

181 : 1, 181

637 : 1, 7, 13, 49, 91, 637

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,637,280,728,397, is 1.

Now, the common factors can be found like this.

181:181

637:7x 7x 13

280:2x 2x 2x 5x 7

728:2x 2x 2x 7x 13

397:397

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 2x 7x 7x 13 = 5096

Therefore, the value for common factors is 5096.

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 = 9330349770560/(1x5096)

LCM = 9330349770560/5096

LCM = 1830916360

Thus, we can understand that the LCM of 181,637,280,728,397 is 1830916360.
