Given numbers are 638,143,867,515

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

The LCM of 638,143,867,515 is 3703312470.

Find LCM of 638,143,867,515 with Prime Factorization

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

11 x 58 x 13 x 867 x 515 = 3703312470

Therefore, the lowest common multiple of 638,143,867,515 is 3703312470.

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 143 x 867 x 515 = 40736437170

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

143 : 1, 11, 13, 143

867 : 1, 3, 17, 51, 289, 867

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,143,867,515, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

143:11x 13

867:3x 17x 17

515:5x 103

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

11 = 11

Therefore, the value for common factors is 11.

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 = 40736437170/(1x11)

LCM = 40736437170/11

LCM = 3703312470

Thus, we can understand that the LCM of 638,143,867,515 is 3703312470.
