Given numbers are 905,129,807,721

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

The LCM of 905,129,807,721 is 22642576005.

Find LCM of 905,129,807,721 with Prime Factorization

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

3 x 905 x 43 x 269 x 721 = 22642576005

Therefore, the lowest common multiple of 905,129,807,721 is 22642576005.

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.

905 x 129 x 807 x 721 = 67927728015

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.

905 : 1, 5, 181, 905

129 : 1, 3, 43, 129

807 : 1, 3, 269, 807

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,129,807,721, is 1.

Now, the common factors can be found like this.

905:5x 181

129:3x 43

807:3x 269

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.

3 = 3

Therefore, the value for common factors is 3.

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 = 67927728015/(1x3)

LCM = 67927728015/3

LCM = 22642576005

Thus, we can understand that the LCM of 905,129,807,721 is 22642576005.

Here are some samples of LCM of two or more Numbers calculations.
