Given numbers are 689,653,715,439

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

The LCM of 689,653,715,439 is 10863245965.

Find LCM of 689,653,715,439 with Prime Factorization

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

13 x 53 x 653 x 55 x 439 = 10863245965

Therefore, the lowest common multiple of 689,653,715,439 is 10863245965.

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 653 x 715 x 439 = 141222197545

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

653 : 1, 653

715 : 1, 5, 11, 13, 55, 65, 143, 715

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,653,715,439, is 1.

Now, the common factors can be found like this.

689:13x 53

653:653

715:5x 11x 13

439:439

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 = 141222197545/(1x13)

LCM = 141222197545/13

LCM = 10863245965

Thus, we can understand that the LCM of 689,653,715,439 is 10863245965.
