Given numbers are 638,488,301,172

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

The LCM of 638,488,301,172 is 46857272.

Find LCM of 638,488,301,172 with Prime Factorization

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

2 x 2 x 43 x 319 x 122 x 7 x 1 = 46857272

Therefore, the lowest common multiple of 638,488,301,172 is 46857272.

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 488 x 301 x 172 = 16118901568

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

488 : 1, 2, 4, 8, 61, 122, 244, 488

301 : 1, 7, 43, 301

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,488,301,172, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

488:2x 2x 2x 61

301:7x 43

172:2x 2x 43

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 43 = 344

Therefore, the value for common factors is 344.

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 = 16118901568/(1x344)

LCM = 16118901568/344

LCM = 46857272

Thus, we can understand that the LCM of 638,488,301,172 is 46857272.
