Given numbers are 642,963,579,185

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

The LCM of 642,963,579,185 is 68767830.

Find LCM of 642,963,579,185 with Prime Factorization

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

3 x 107 x 2 x 3 x 193 x 185 = 68767830

Therefore, the lowest common multiple of 642,963,579,185 is 68767830.

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.

642 x 963 x 579 x 185 = 66223420290

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

579 : 1, 3, 193, 579

185 : 1, 5, 37, 185

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,963,579,185, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

963:3x 3x 107

579:3x 193

185:5x 37

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 107 = 963

Therefore, the value for common factors is 963.

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 = 66223420290/(1x963)

LCM = 66223420290/963

LCM = 68767830

Thus, we can understand that the LCM of 642,963,579,185 is 68767830.
