Given numbers are 891,921,794,455

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

The LCM of 891,921,794,455 is 98820711990.

Find LCM of 891,921,794,455 with Prime Factorization

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

3 x 297 x 307 x 794 x 455 = 98820711990

Therefore, the lowest common multiple of 891,921,794,455 is 98820711990.

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.

891 x 921 x 794 x 455 = 296462135970

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

921 : 1, 3, 307, 921

794 : 1, 2, 397, 794

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,921,794,455, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

921:3x 307

794:2x 397

455:5x 7x 13

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 = 296462135970/(1x3)

LCM = 296462135970/3

LCM = 98820711990

Thus, we can understand that the LCM of 891,921,794,455 is 98820711990.
