Given numbers are 783,336,921,390

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

The LCM of 783,336,921,390 is 1749973680.

Find LCM of 783,336,921,390 with Prime Factorization

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

2 x 3 x 261 x 56 x 307 x 65 = 1749973680

Therefore, the lowest common multiple of 783,336,921,390 is 1749973680.

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 336 x 921 x 390 = 94498578720

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

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

921 : 1, 3, 307, 921

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,336,921,390, is 3.

Now, the common factors can be found like this.

783:3x 3x 3x 29

336:2x 2x 2x 2x 3x 7

921:3x 307

390:2x 3x 5x 13

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 94498578720/(3x18)

LCM = 94498578720/54

LCM = 1749973680

Thus, we can understand that the LCM of 783,336,921,390 is 1749973680.
