Given numbers are 421,878,421,569

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

The LCM of 421,878,421,569 is 210324022.

Find LCM of 421,878,421,569 with Prime Factorization

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

421 x 1 x 878 x 1 x 569 = 210324022

Therefore, the lowest common multiple of 421,878,421,569 is 210324022.

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 878 x 421 x 569 = 88546413262

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

878 : 1, 2, 439, 878

421 : 1, 421

569 : 1, 569

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,878,421,569, is 1.

Now, the common factors can be found like this.

421:421

878:2x 439

421:421

569:569

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

421 = 421

Therefore, the value for common factors is 421.

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 = 88546413262/(1x421)

LCM = 88546413262/421

LCM = 210324022

Thus, we can understand that the LCM of 421,878,421,569 is 210324022.
