Given numbers are 115,412,809,721

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

The LCM of 115,412,809,721 is 268312940.

Find LCM of 115,412,809,721 with Prime Factorization

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

103 x 115 x 4 x 809 x 7 = 268312940

Therefore, the lowest common multiple of 115,412,809,721 is 268312940.

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.

115 x 412 x 809 x 721 = 27636232820

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.

115 : 1, 5, 23, 115

412 : 1, 2, 4, 103, 206, 412

809 : 1, 809

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,412,809,721, is 1.

Now, the common factors can be found like this.

115:5x 23

412:2x 2x 103

809:809

721:7x 103

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

103 = 103

Therefore, the value for common factors is 103.

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 = 27636232820/(1x103)

LCM = 27636232820/103

LCM = 268312940

Thus, we can understand that the LCM of 115,412,809,721 is 268312940.
