Given numbers are 489,436,545,103

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

The LCM of 489,436,545,103 is 109800060.

Find LCM of 489,436,545,103 with Prime Factorization

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

109 x 489 x 4 x 5 x 103 = 109800060

Therefore, the lowest common multiple of 489,436,545,103 is 109800060.

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.

489 x 436 x 545 x 103 = 11968206540

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.

489 : 1, 3, 163, 489

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

545 : 1, 5, 109, 545

103 : 1, 103

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,436,545,103, is 1.

Now, the common factors can be found like this.

489:3x 163

436:2x 2x 109

545:5x 109

103:103

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 = 11968206540/(1x109)

LCM = 11968206540/109

LCM = 109800060

Thus, we can understand that the LCM of 489,436,545,103 is 109800060.
