Given numbers are 642,304,817,194,192

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

The LCM of 642,304,817,194,192 is 1628091456.

Find LCM of 642,304,817,194,192 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 19 x 107 x 1 x 43 x 97 x 4 = 1628091456

Therefore, the lowest common multiple of 642,304,817,194,192 is 1628091456.

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 304 x 817 x 194 x 192 = 5939277631488

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

304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304

817 : 1, 19, 43, 817

194 : 1, 2, 97, 194

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,304,817,194,192, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

304:2x 2x 2x 2x 19

817:19x 43

194:2x 97

192:2x 2x 2x 2x 2x 2x 3

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 2x 2x 2x 2x 3x 19 = 3648

Therefore, the value for common factors is 3648.

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 = 5939277631488/(1x3648)

LCM = 5939277631488/3648

LCM = 1628091456

Thus, we can understand that the LCM of 642,304,817,194,192 is 1628091456.
