Given numbers are 687,469,806,728,546

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

The LCM of 687,469,806,728,546 is 1038782472.

Find LCM of 687,469,806,728,546 with Prime Factorization

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

2 x 3 x 7 x 13 x 229 x 67 x 31 x 4 x 1 = 1038782472

Therefore, the lowest common multiple of 687,469,806,728,546 is 1038782472.

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.

687 x 469 x 806 x 728 x 546 = 103225891807584

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.

687 : 1, 3, 229, 687

469 : 1, 7, 67, 469

806 : 1, 2, 13, 26, 31, 62, 403, 806

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

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 687,469,806,728,546, is 1.

Now, the common factors can be found like this.

687:3x 229

469:7x 67

806:2x 13x 31

728:2x 2x 2x 7x 13

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 2x 3x 7x 7x 13x 13 = 99372

Therefore, the value for common factors is 99372.

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 = 103225891807584/(1x99372)

LCM = 103225891807584/99372

LCM = 1038782472

Thus, we can understand that the LCM of 687,469,806,728,546 is 1038782472.
