Given numbers are 678,805,381,847

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

The LCM of 678,805,381,847 is 8387154930.

Find LCM of 678,805,381,847 with Prime Factorization

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

3 x 7 x 226 x 115 x 127 x 121 = 8387154930

Therefore, the lowest common multiple of 678,805,381,847 is 8387154930.

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.

678 x 805 x 381 x 847 = 176130253530

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

805 : 1, 5, 7, 23, 35, 115, 161, 805

381 : 1, 3, 127, 381

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,805,381,847, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

805:5x 7x 23

381:3x 127

847:7x 11x 11

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 176130253530/(1x21)

LCM = 176130253530/21

LCM = 8387154930

Thus, we can understand that the LCM of 678,805,381,847 is 8387154930.
