Given numbers are 391,504,671,546

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

The LCM of 391,504,671,546 is 1718989272.

Find LCM of 391,504,671,546 with Prime Factorization

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

2 x 3 x 7 x 391 x 12 x 671 x 13 = 1718989272

Therefore, the lowest common multiple of 391,504,671,546 is 1718989272.

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.

391 x 504 x 671 x 546 = 72197549424

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.

391 : 1, 17, 23, 391

504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504

671 : 1, 11, 61, 671

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,504,671,546, is 1.

Now, the common factors can be found like this.

391:17x 23

504:2x 2x 2x 3x 3x 7

671:11x 61

546:2x 3x 7x 13

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

2x 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 72197549424/(1x42)

LCM = 72197549424/42

LCM = 1718989272

Thus, we can understand that the LCM of 391,504,671,546 is 1718989272.
