Given numbers are 561,919,442,668

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

The LCM of 561,919,442,668 is 4477114356.

Find LCM of 561,919,442,668 with Prime Factorization

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

2 x 17 x 33 x 919 x 13 x 334 = 4477114356

Therefore, the lowest common multiple of 561,919,442,668 is 4477114356.

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.

561 x 919 x 442 x 668 = 152221888104

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

919 : 1, 919

442 : 1, 2, 13, 17, 26, 34, 221, 442

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,919,442,668, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

919:919

442:2x 13x 17

668:2x 2x 167

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 152221888104/(1x34)

LCM = 152221888104/34

LCM = 4477114356

Thus, we can understand that the LCM of 561,919,442,668 is 4477114356.
