Given numbers are 489,507,545,161

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

The LCM of 489,507,545,161 is 7251334545.

Find LCM of 489,507,545,161 with Prime Factorization

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

3 x 163 x 169 x 545 x 161 = 7251334545

Therefore, the lowest common multiple of 489,507,545,161 is 7251334545.

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 507 x 545 x 161 = 21754003635

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

507 : 1, 3, 13, 39, 169, 507

545 : 1, 5, 109, 545

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,507,545,161, is 1.

Now, the common factors can be found like this.

489:3x 163

507:3x 13x 13

545:5x 109

161:7x 23

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

3 = 3

Therefore, the value for common factors is 3.

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 = 21754003635/(1x3)

LCM = 21754003635/3

LCM = 7251334545

Thus, we can understand that the LCM of 489,507,545,161 is 7251334545.
