Given numbers are 638,432,803,156

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

The LCM of 638,432,803,156 is 130779792.

Find LCM of 638,432,803,156 with Prime Factorization

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

2 x 2 x 3 x 11 x 29 x 36 x 73 x 13 = 130779792

Therefore, the lowest common multiple of 638,432,803,156 is 130779792.

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 432 x 803 x 156 = 34525865088

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

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

803 : 1, 11, 73, 803

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,432,803,156, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

432:2x 2x 2x 2x 3x 3x 3

803:11x 73

156:2x 2x 3x 13

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 3x 11 = 264

Therefore, the value for common factors is 264.

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 = 34525865088/(1x264)

LCM = 34525865088/264

LCM = 130779792

Thus, we can understand that the LCM of 638,432,803,156 is 130779792.
