Given numbers are 431,391,219,993

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

The LCM of 431,391,219,993 is 12215918769.

Find LCM of 431,391,219,993 with Prime Factorization

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

3 x 431 x 391 x 73 x 331 = 12215918769

Therefore, the lowest common multiple of 431,391,219,993 is 12215918769.

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.

431 x 391 x 219 x 993 = 36647756307

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.

431 : 1, 431

391 : 1, 17, 23, 391

219 : 1, 3, 73, 219

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,391,219,993, is 1.

Now, the common factors can be found like this.

431:431

391:17x 23

219:3x 73

993:3x 331

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

3 = 3

Therefore, the value for common factors is 3.

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 = 36647756307/(1x3)

LCM = 36647756307/3

LCM = 12215918769

Thus, we can understand that the LCM of 431,391,219,993 is 12215918769.
