Given numbers are 581,721,927,778

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

The LCM of 581,721,927,778 is 419020686.

Find LCM of 581,721,927,778 with Prime Factorization

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

7 x 103 x 83 x 1 x 9 x 778 = 419020686

Therefore, the lowest common multiple of 581,721,927,778 is 419020686.

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.

581 x 721 x 927 x 778 = 302113914606

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.

581 : 1, 7, 83, 581

721 : 1, 7, 103, 721

927 : 1, 3, 9, 103, 309, 927

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,721,927,778, is 1.

Now, the common factors can be found like this.

581:7x 83

721:7x 103

927:3x 3x 103

778:2x 389

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

7x 103 = 721

Therefore, the value for common factors is 721.

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 = 302113914606/(1x721)

LCM = 302113914606/721

LCM = 419020686

Thus, we can understand that the LCM of 581,721,927,778 is 419020686.
