Given numbers are 638,429,853,394

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

The LCM of 638,429,853,394 is 4181196162.

Find LCM of 638,429,853,394 with Prime Factorization

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

2 x 11 x 29 x 39 x 853 x 197 = 4181196162

Therefore, the lowest common multiple of 638,429,853,394 is 4181196162.

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.

638 x 429 x 853 x 394 = 91986315564

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.

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

429 : 1, 3, 11, 13, 33, 39, 143, 429

853 : 1, 853

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,429,853,394, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

429:3x 11x 13

853:853

394:2x 197

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 = 91986315564/(1x22)

LCM = 91986315564/22

LCM = 4181196162

Thus, we can understand that the LCM of 638,429,853,394 is 4181196162.
