Given numbers are 639,375,852,687,431

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

The LCM of 639,375,852,687,431 is 31534330500.

Find LCM of 639,375,852,687,431 with Prime Factorization

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

3 x 71 x 3 x 125 x 4 x 229 x 431 = 31534330500

Therefore, the lowest common multiple of 639,375,852,687,431 is 31534330500.

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.

639 x 375 x 852 x 687 x 431 = 60451311568500

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.

639 : 1, 3, 9, 71, 213, 639

375 : 1, 3, 5, 15, 25, 75, 125, 375

852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852

687 : 1, 3, 229, 687

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,375,852,687,431, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

375:3x 5x 5x 5

852:2x 2x 3x 71

687:3x 229

431:431

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

3x 3x 3x 71 = 1917

Therefore, the value for common factors is 1917.

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 = 60451311568500/(1x1917)

LCM = 60451311568500/1917

LCM = 31534330500

Thus, we can understand that the LCM of 639,375,852,687,431 is 31534330500.
