Given numbers are 921,660,275,920,905

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

The LCM of 921,660,275,920,905 is 8435070600.

Find LCM of 921,660,275,920,905 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 307 x 1 x 5 x 46 x 181 = 8435070600

Therefore, the lowest common multiple of 921,660,275,920,905 is 8435070600.

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.

921 x 660 x 275 x 920 x 905 = 139178664900000

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.

921 : 1, 3, 307, 921

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

275 : 1, 5, 11, 25, 55, 275

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,660,275,920,905, is 1.

Now, the common factors can be found like this.

921:3x 307

660:2x 2x 3x 5x 11

275:5x 5x 11

920:2x 2x 2x 5x 23

905:5x 181

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

2x 2x 3x 5x 5x 5x 11 = 16500

Therefore, the value for common factors is 16500.

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 = 139178664900000/(1x16500)

LCM = 139178664900000/16500

LCM = 8435070600

Thus, we can understand that the LCM of 921,660,275,920,905 is 8435070600.
