Given numbers are 489,621,109,436

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

The LCM of 489,621,109,436 is 44133228.

Find LCM of 489,621,109,436 with Prime Factorization

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

3 x 109 x 163 x 207 x 1 x 4 = 44133228

Therefore, the lowest common multiple of 489,621,109,436 is 44133228.

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 621 x 109 x 436 = 14431565556

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

621 : 1, 3, 9, 23, 27, 69, 207, 621

109 : 1, 109

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,621,109,436, is 1.

Now, the common factors can be found like this.

489:3x 163

621:3x 3x 3x 23

109:109

436:2x 2x 109

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

3x 109 = 327

Therefore, the value for common factors is 327.

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 = 14431565556/(1x327)

LCM = 14431565556/327

LCM = 44133228

Thus, we can understand that the LCM of 489,621,109,436 is 44133228.
