Given numbers are 221,650,449,381

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

The LCM of 221,650,449,381 is 1890312450.

Find LCM of 221,650,449,381 with Prime Factorization

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

13 x 17 x 50 x 449 x 381 = 1890312450

Therefore, the lowest common multiple of 221,650,449,381 is 1890312450.

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.

221 x 650 x 449 x 381 = 24574061850

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.

221 : 1, 13, 17, 221

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

449 : 1, 449

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,650,449,381, is 1.

Now, the common factors can be found like this.

221:13x 17

650:2x 5x 5x 13

449:449

381:3x 127

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

13 = 13

Therefore, the value for common factors is 13.

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 = 24574061850/(1x13)

LCM = 24574061850/13

LCM = 1890312450

Thus, we can understand that the LCM of 221,650,449,381 is 1890312450.
