Given numbers are 210,391,104,421

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

The LCM of 210,391,104,421 is 1797552120.

Find LCM of 210,391,104,421 with Prime Factorization

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

2 x 105 x 391 x 52 x 421 = 1797552120

Therefore, the lowest common multiple of 210,391,104,421 is 1797552120.

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.

210 x 391 x 104 x 421 = 3595104240

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.

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

391 : 1, 17, 23, 391

104 : 1, 2, 4, 8, 13, 26, 52, 104

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,391,104,421, is 1.

Now, the common factors can be found like this.

210:2x 3x 5x 7

391:17x 23

104:2x 2x 2x 13

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 3595104240/(1x2)

LCM = 3595104240/2

LCM = 1797552120

Thus, we can understand that the LCM of 210,391,104,421 is 1797552120.
