Given numbers are 517,389,436,545

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

The LCM of 517,389,436,545 is 438426340.

Find LCM of 517,389,436,545 with Prime Factorization

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

109 x 517 x 389 x 4 x 5 = 438426340

Therefore, the lowest common multiple of 517,389,436,545 is 438426340.

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.

517 x 389 x 436 x 545 = 47788471060

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.

517 : 1, 11, 47, 517

389 : 1, 389

436 : 1, 2, 4, 109, 218, 436

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,389,436,545, is 1.

Now, the common factors can be found like this.

517:11x 47

389:389

436:2x 2x 109

545:5x 109

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

109 = 109

Therefore, the value for common factors is 109.

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 = 47788471060/(1x109)

LCM = 47788471060/109

LCM = 438426340

Thus, we can understand that the LCM of 517,389,436,545 is 438426340.
