Given numbers are 638,264,841,516,670

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

The LCM of 638,264,841,516,670 is 3198255720.

Find LCM of 638,264,841,516,670 with Prime Factorization

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

2 x 2 x 3 x 11 x 29 x 1 x 2 x 29 x 43 x 335 = 3198255720

Therefore, the lowest common multiple of 638,264,841,516,670 is 3198255720.

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 264 x 841 x 516 x 670 = 48971691584640

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

264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264

841 : 1, 29, 841

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,264,841,516,670, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

264:2x 2x 2x 3x 11

841:29x 29

516:2x 2x 3x 43

670:2x 5x 67

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 2x 3x 11x 29 = 15312

Therefore, the value for common factors is 15312.

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 = 48971691584640/(1x15312)

LCM = 48971691584640/15312

LCM = 3198255720

Thus, we can understand that the LCM of 638,264,841,516,670 is 3198255720.
