Given numbers are 395,642,325,643,421

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

The LCM of 395,642,325,643,421 is 4462092295050.

Find LCM of 395,642,325,643,421 with Prime Factorization

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

5 x 79 x 642 x 65 x 643 x 421 = 4462092295050

Therefore, the lowest common multiple of 395,642,325,643,421 is 4462092295050.

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.

395 x 642 x 325 x 643 x 421 = 22310461475250

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.

395 : 1, 5, 79, 395

642 : 1, 2, 3, 6, 107, 214, 321, 642

325 : 1, 5, 13, 25, 65, 325

643 : 1, 643

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,642,325,643,421, is 1.

Now, the common factors can be found like this.

395:5x 79

642:2x 3x 107

325:5x 5x 13

643:643

421:421

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

5 = 5

Therefore, the value for common factors is 5.

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 = 22310461475250/(1x5)

LCM = 22310461475250/5

LCM = 4462092295050

Thus, we can understand that the LCM of 395,642,325,643,421 is 4462092295050.
