Given numbers are 643,309,747,618

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

The LCM of 643,309,747,618 is 98946126.

Find LCM of 643,309,747,618 with Prime Factorization

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

3 x 103 x 643 x 1 x 249 x 2 = 98946126

Therefore, the lowest common multiple of 643,309,747,618 is 98946126.

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 309 x 747 x 618 = 91723058802

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

309 : 1, 3, 103, 309

747 : 1, 3, 9, 83, 249, 747

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,309,747,618, is 1.

Now, the common factors can be found like this.

643:643

309:3x 103

747:3x 3x 83

618:2x 3x 103

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

3x 3x 103 = 927

Therefore, the value for common factors is 927.

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 = 91723058802/(1x927)

LCM = 91723058802/927

LCM = 98946126

Thus, we can understand that the LCM of 643,309,747,618 is 98946126.
