Given numbers are 918,643,629

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

The LCM of 918,643,629 is 21840138.

Find LCM of 918,643,629 with Prime Factorization

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

17 x 54 x 643 x 37 = 21840138

Therefore, the lowest common multiple of 918,643,629 is 21840138.

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.

918 x 643 x 629 = 371282346

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.

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

643 : 1, 643

629 : 1, 17, 37, 629

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,643,629, is 1.

Now, the common factors can be found like this.

918:2x 3x 3x 3x 17

643:643

629:17x 37

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

17 = 17

Therefore, the value for common factors is 17.

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 = 371282346/(1x17)

LCM = 371282346/17

LCM = 21840138

Thus, we can understand that the LCM of 918,643,629 is 21840138.

Here are some samples of LCM of two or more Numbers calculations.
