Given numbers are 783,347,445,217,921

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

The LCM of 783,347,445,217,921 is 8054699768955.

Find LCM of 783,347,445,217,921 with Prime Factorization

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

3 x 261 x 347 x 445 x 217 x 307 = 8054699768955

Therefore, the lowest common multiple of 783,347,445,217,921 is 8054699768955.

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.

783 x 347 x 445 x 217 x 921 = 24164099306865

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.

783 : 1, 3, 9, 27, 29, 87, 261, 783

347 : 1, 347

445 : 1, 5, 89, 445

217 : 1, 7, 31, 217

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,347,445,217,921, is 1.

Now, the common factors can be found like this.

783:3x 3x 3x 29

347:347

445:5x 89

217:7x 31

921:3x 307

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 = 24164099306865/(1x3)

LCM = 24164099306865/3

LCM = 8054699768955

Thus, we can understand that the LCM of 783,347,445,217,921 is 8054699768955.
