Given numbers are 817,989,774,331

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

The LCM of 817,989,774,331 is 111956778.

Find LCM of 817,989,774,331 with Prime Factorization

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

43 x 19 x 23 x 18 x 331 = 111956778

Therefore, the lowest common multiple of 817,989,774,331 is 111956778.

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.

817 x 989 x 774 x 331 = 207008082522

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.

817 : 1, 19, 43, 817

989 : 1, 23, 43, 989

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

331 : 1, 331

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,989,774,331, is 1.

Now, the common factors can be found like this.

817:19x 43

989:23x 43

774:2x 3x 3x 43

331:331

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

43x 43 = 1849

Therefore, the value for common factors is 1849.

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 = 207008082522/(1x1849)

LCM = 207008082522/1849

LCM = 111956778

Thus, we can understand that the LCM of 817,989,774,331 is 111956778.
