Given numbers are 891,557,767,421,315

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

The LCM of 891,557,767,421,315 is 5608909120815.

Find LCM of 891,557,767,421,315 with Prime Factorization

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

3 x 3 x 99 x 557 x 767 x 421 x 35 = 5608909120815

Therefore, the lowest common multiple of 891,557,767,421,315 is 5608909120815.

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 557 x 767 x 421 x 315 = 50480182087335

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

557 : 1, 557

767 : 1, 13, 59, 767

421 : 1, 421

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,557,767,421,315, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

557:557

767:13x 59

421:421

315:3x 3x 5x 7

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 50480182087335/(1x9)

LCM = 50480182087335/9

LCM = 5608909120815

Thus, we can understand that the LCM of 891,557,767,421,315 is 5608909120815.
