Given numbers are 221,872,323,425

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

The LCM of 221,872,323,425 is 91538200.

Find LCM of 221,872,323,425 with Prime Factorization

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

17 x 13 x 872 x 19 x 25 = 91538200

Therefore, the lowest common multiple of 221,872,323,425 is 91538200.

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 872 x 323 x 425 = 26454539800

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

872 : 1, 2, 4, 8, 109, 218, 436, 872

323 : 1, 17, 19, 323

425 : 1, 5, 17, 25, 85, 425

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,872,323,425, is 1.

Now, the common factors can be found like this.

221:13x 17

872:2x 2x 2x 109

323:17x 19

425:5x 5x 17

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

17x 17 = 289

Therefore, the value for common factors is 289.

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 = 26454539800/(1x289)

LCM = 26454539800/289

LCM = 91538200

Thus, we can understand that the LCM of 221,872,323,425 is 91538200.
