Given numbers are 391,529,207,421

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

The LCM of 391,529,207,421 is 34074477.

Find LCM of 391,529,207,421 with Prime Factorization

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

23 x 17 x 23 x 9 x 421 = 34074477

Therefore, the lowest common multiple of 391,529,207,421 is 34074477.

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.

391 x 529 x 207 x 421 = 18025398333

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.

391 : 1, 17, 23, 391

529 : 1, 23, 529

207 : 1, 3, 9, 23, 69, 207

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,529,207,421, is 1.

Now, the common factors can be found like this.

391:17x 23

529:23x 23

207:3x 3x 23

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.

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 18025398333/(1x529)

LCM = 18025398333/529

LCM = 34074477

Thus, we can understand that the LCM of 391,529,207,421 is 34074477.
