Given numbers are 421,745,389,298

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

The LCM of 421,745,389,298 is 244015810.

Find LCM of 421,745,389,298 with Prime Factorization

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

149 x 421 x 5 x 389 x 2 = 244015810

Therefore, the lowest common multiple of 421,745,389,298 is 244015810.

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 745 x 389 x 298 = 36358355690

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

745 : 1, 5, 149, 745

389 : 1, 389

298 : 1, 2, 149, 298

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,745,389,298, is 1.

Now, the common factors can be found like this.

421:421

745:5x 149

389:389

298:2x 149

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

149 = 149

Therefore, the value for common factors is 149.

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 = 36358355690/(1x149)

LCM = 36358355690/149

LCM = 244015810

Thus, we can understand that the LCM of 421,745,389,298 is 244015810.
