Given numbers are 163,638,576,642

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

The LCM of 163,638,576,642 is 3204679104.

Find LCM of 163,638,576,642 with Prime Factorization

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

2 x 3 x 163 x 319 x 96 x 107 = 3204679104

Therefore, the lowest common multiple of 163,638,576,642 is 3204679104.

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.

163 x 638 x 576 x 642 = 38456149248

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.

163 : 1, 163

638 : 1, 2, 11, 22, 29, 58, 319, 638

576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,638,576,642, is 1.

Now, the common factors can be found like this.

163:163

638:2x 11x 29

576:2x 2x 2x 2x 2x 2x 3x 3

642:2x 3x 107

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 38456149248/(1x12)

LCM = 38456149248/12

LCM = 3204679104

Thus, we can understand that the LCM of 163,638,576,642 is 3204679104.
