Given numbers are 421,379,426,319,747

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

The LCM of 421,379,426,319,747 is 5399094575754.

Find LCM of 421,379,426,319,747 with Prime Factorization

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

3 x 421 x 379 x 142 x 319 x 249 = 5399094575754

Therefore, the lowest common multiple of 421,379,426,319,747 is 5399094575754.

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 379 x 426 x 319 x 747 = 16197283727262

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

379 : 1, 379

426 : 1, 2, 3, 6, 71, 142, 213, 426

319 : 1, 11, 29, 319

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,379,426,319,747, is 1.

Now, the common factors can be found like this.

421:421

379:379

426:2x 3x 71

319:11x 29

747:3x 3x 83

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 = 16197283727262/(1x3)

LCM = 16197283727262/3

LCM = 5399094575754

Thus, we can understand that the LCM of 421,379,426,319,747 is 5399094575754.
