Given numbers are 396,676,319,728,671

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

The LCM of 396,676,319,728,671 is 1657439784.

Find LCM of 396,676,319,728,671 with Prime Factorization

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

2 x 2 x 11 x 13 x 9 x 13 x 29 x 14 x 61 = 1657439784

Therefore, the lowest common multiple of 396,676,319,728,671 is 1657439784.

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.

396 x 676 x 319 x 728 x 671 = 41714444483712

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.

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

319 : 1, 11, 29, 319

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

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,676,319,728,671, is 1.

Now, the common factors can be found like this.

396:2x 2x 3x 3x 11

676:2x 2x 13x 13

319:11x 29

728:2x 2x 2x 7x 13

671:11x 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 2x 2x 11x 11x 13 = 25168

Therefore, the value for common factors is 25168.

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 = 41714444483712/(1x25168)

LCM = 41714444483712/25168

LCM = 1657439784

Thus, we can understand that the LCM of 396,676,319,728,671 is 1657439784.
