Given numbers are 691,545,542,813

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

The LCM of 691,545,542,813 is 612343470.

Find LCM of 691,545,542,813 with Prime Factorization

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

271 x 691 x 545 x 2 x 3 = 612343470

Therefore, the lowest common multiple of 691,545,542,813 is 612343470.

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.

691 x 545 x 542 x 813 = 165945080370

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.

691 : 1, 691

545 : 1, 5, 109, 545

542 : 1, 2, 271, 542

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,545,542,813, is 1.

Now, the common factors can be found like this.

691:691

545:5x 109

542:2x 271

813:3x 271

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

271 = 271

Therefore, the value for common factors is 271.

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 = 165945080370/(1x271)

LCM = 165945080370/271

LCM = 612343470

Thus, we can understand that the LCM of 691,545,542,813 is 612343470.
