Given numbers are 641,558,641,839

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

The LCM of 641,558,641,839 is 300091842.

Find LCM of 641,558,641,839 with Prime Factorization

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

641 x 1 x 558 x 1 x 839 = 300091842

Therefore, the lowest common multiple of 641,558,641,839 is 300091842.

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.

641 x 558 x 641 x 839 = 192358870722

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.

641 : 1, 641

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

641 : 1, 641

839 : 1, 839

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,558,641,839, is 1.

Now, the common factors can be found like this.

641:641

558:2x 3x 3x 31

641:641

839:839

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

641 = 641

Therefore, the value for common factors is 641.

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 = 192358870722/(1x641)

LCM = 192358870722/641

LCM = 300091842

Thus, we can understand that the LCM of 641,558,641,839 is 300091842.
