Given numbers are 470,638,431,671

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

The LCM of 470,638,431,671 is 3941809630.

Find LCM of 470,638,431,671 with Prime Factorization

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

2 x 11 x 235 x 29 x 431 x 61 = 3941809630

Therefore, the lowest common multiple of 470,638,431,671 is 3941809630.

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.

470 x 638 x 431 x 671 = 86719811860

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.

470 : 1, 2, 5, 10, 47, 94, 235, 470

638 : 1, 2, 11, 22, 29, 58, 319, 638

431 : 1, 431

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,638,431,671, is 1.

Now, the common factors can be found like this.

470:2x 5x 47

638:2x 11x 29

431:431

671:11x 61

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 86719811860/(1x22)

LCM = 86719811860/22

LCM = 3941809630

Thus, we can understand that the LCM of 470,638,431,671 is 3941809630.
