Given numbers are 643,403,963,327

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

The LCM of 643,403,963,327 is 27199993743.

Find LCM of 643,403,963,327 with Prime Factorization

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

3 x 643 x 403 x 321 x 109 = 27199993743

Therefore, the lowest common multiple of 643,403,963,327 is 27199993743.

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.

643 x 403 x 963 x 327 = 81599981229

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.

643 : 1, 643

403 : 1, 13, 31, 403

963 : 1, 3, 9, 107, 321, 963

327 : 1, 3, 109, 327

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,403,963,327, is 1.

Now, the common factors can be found like this.

643:643

403:13x 31

963:3x 3x 107

327:3x 109

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 = 81599981229/(1x3)

LCM = 81599981229/3

LCM = 27199993743

Thus, we can understand that the LCM of 643,403,963,327 is 27199993743.
