Given numbers are 221,441,646,493

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

The LCM of 221,441,646,493 is 107402022.

Find LCM of 221,441,646,493 with Prime Factorization

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

17 x 13 x 441 x 38 x 29 = 107402022

Therefore, the lowest common multiple of 221,441,646,493 is 107402022.

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 441 x 646 x 493 = 31039184358

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

441 : 1, 3, 7, 9, 21, 49, 63, 147, 441

646 : 1, 2, 17, 19, 34, 38, 323, 646

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,441,646,493, is 1.

Now, the common factors can be found like this.

221:13x 17

441:3x 3x 7x 7

646:2x 17x 19

493:17x 29

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 = 31039184358/(1x289)

LCM = 31039184358/289

LCM = 107402022

Thus, we can understand that the LCM of 221,441,646,493 is 107402022.
