Given numbers are 643,284,703,446,918

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

The LCM of 643,284,703,446,918 is 13140206388252.

Find LCM of 643,284,703,446,918 with Prime Factorization

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

2 x 643 x 142 x 703 x 223 x 459 = 13140206388252

Therefore, the lowest common multiple of 643,284,703,446,918 is 13140206388252.

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 284 x 703 x 446 x 918 = 52560825553008

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

284 : 1, 2, 4, 71, 142, 284

703 : 1, 19, 37, 703

446 : 1, 2, 223, 446

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,284,703,446,918, is 1.

Now, the common factors can be found like this.

643:643

284:2x 2x 71

703:19x 37

446:2x 223

918:2x 3x 3x 3x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 52560825553008/(1x4)

LCM = 52560825553008/4

LCM = 13140206388252

Thus, we can understand that the LCM of 643,284,703,446,918 is 13140206388252.
