Given numbers are 138,464,401,638

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

The LCM of 138,464,401,638 is 141222576.

Find LCM of 138,464,401,638 with Prime Factorization

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

2 x 29 x 69 x 8 x 401 x 11 = 141222576

Therefore, the lowest common multiple of 138,464,401,638 is 141222576.

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.

138 x 464 x 401 x 638 = 16381818816

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

401 : 1, 401

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,464,401,638, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

464:2x 2x 2x 2x 29

401:401

638:2x 11x 29

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 29 = 116

Therefore, the value for common factors is 116.

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 = 16381818816/(1x116)

LCM = 16381818816/116

LCM = 141222576

Thus, we can understand that the LCM of 138,464,401,638 is 141222576.
