Given numbers are 909,808,961,921

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

The LCM of 909,808,961,921 is 2145436344.

Find LCM of 909,808,961,921 with Prime Factorization

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

3 x 101 x 3 x 8 x 961 x 307 = 2145436344

Therefore, the lowest common multiple of 909,808,961,921 is 2145436344.

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.

909 x 808 x 961 x 921 = 650067212232

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.

909 : 1, 3, 9, 101, 303, 909

808 : 1, 2, 4, 8, 101, 202, 404, 808

961 : 1, 31, 961

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,808,961,921, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

808:2x 2x 2x 101

961:31x 31

921:3x 307

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

3x 101 = 303

Therefore, the value for common factors is 303.

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 = 650067212232/(1x303)

LCM = 650067212232/303

LCM = 2145436344

Thus, we can understand that the LCM of 909,808,961,921 is 2145436344.
