Given numbers are 421,391,335,365

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

The LCM of 421,391,335,365 is 4025562005.

Find LCM of 421,391,335,365 with Prime Factorization

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

5 x 421 x 391 x 67 x 73 = 4025562005

Therefore, the lowest common multiple of 421,391,335,365 is 4025562005.

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.

421 x 391 x 335 x 365 = 20127810025

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.

421 : 1, 421

391 : 1, 17, 23, 391

335 : 1, 5, 67, 335

365 : 1, 5, 73, 365

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,391,335,365, is 1.

Now, the common factors can be found like this.

421:421

391:17x 23

335:5x 67

365:5x 73

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 = 20127810025/(1x5)

LCM = 20127810025/5

LCM = 4025562005

Thus, we can understand that the LCM of 421,391,335,365 is 4025562005.
