Given numbers are 478,109,436,268

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

The LCM of 478,109,436,268 is 6981668.

Find LCM of 478,109,436,268 with Prime Factorization

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

2 x 2 x 109 x 239 x 1 x 1 x 67 = 6981668

Therefore, the lowest common multiple of 478,109,436,268 is 6981668.

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.

478 x 109 x 436 x 268 = 6088014496

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.

478 : 1, 2, 239, 478

109 : 1, 109

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

268 : 1, 2, 4, 67, 134, 268

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,109,436,268, is 1.

Now, the common factors can be found like this.

478:2x 239

109:109

436:2x 2x 109

268:2x 2x 67

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

2x 2x 2x 109 = 872

Therefore, the value for common factors is 872.

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 = 6088014496/(1x872)

LCM = 6088014496/872

LCM = 6981668

Thus, we can understand that the LCM of 478,109,436,268 is 6981668.
