Given numbers are 689,473,687,910

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

The LCM of 689,473,687,910 is 15672386730.

Find LCM of 689,473,687,910 with Prime Factorization

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

13 x 53 x 473 x 687 x 70 = 15672386730

Therefore, the lowest common multiple of 689,473,687,910 is 15672386730.

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.

689 x 473 x 687 x 910 = 203741027490

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.

689 : 1, 13, 53, 689

473 : 1, 11, 43, 473

687 : 1, 3, 229, 687

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,473,687,910, is 1.

Now, the common factors can be found like this.

689:13x 53

473:11x 43

687:3x 229

910:2x 5x 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.

13 = 13

Therefore, the value for common factors is 13.

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 = 203741027490/(1x13)

LCM = 203741027490/13

LCM = 15672386730

Thus, we can understand that the LCM of 689,473,687,910 is 15672386730.
