Given numbers are 561,639,919,919

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

The LCM of 561,639,919,919 is 109814067.

Find LCM of 561,639,919,919 with Prime Factorization

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

3 x 919 x 187 x 213 x 1 x 1 = 109814067

Therefore, the lowest common multiple of 561,639,919,919 is 109814067.

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 639 x 919 x 919 = 302757382719

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

639 : 1, 3, 9, 71, 213, 639

919 : 1, 919

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,639,919,919, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

639:3x 3x 71

919:919

919:919

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

3x 919 = 2757

Therefore, the value for common factors is 2757.

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 = 302757382719/(1x2757)

LCM = 302757382719/2757

LCM = 109814067

Thus, we can understand that the LCM of 561,639,919,919 is 109814067.
