Given numbers are 478,391,203,667

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

The LCM of 478,391,203,667 is 37940294.

Find LCM of 478,391,203,667 with Prime Factorization

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

23 x 29 x 478 x 17 x 7 x 1 = 37940294

Therefore, the lowest common multiple of 478,391,203,667 is 37940294.

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 391 x 203 x 667 = 25306176098

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

391 : 1, 17, 23, 391

203 : 1, 7, 29, 203

667 : 1, 23, 29, 667

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,391,203,667, is 1.

Now, the common factors can be found like this.

478:2x 239

391:17x 23

203:7x 29

667:23x 29

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

23x 29 = 667

Therefore, the value for common factors is 667.

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 = 25306176098/(1x667)

LCM = 25306176098/667

LCM = 37940294

Thus, we can understand that the LCM of 478,391,203,667 is 37940294.
