Given numbers are 778,246,128,670,819

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

The LCM of 778,246,128,670,819 is 560108465280.

Find LCM of 778,246,128,670,819 with Prime Factorization

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

2 x 3 x 389 x 41 x 64 x 335 x 273 = 560108465280

Therefore, the lowest common multiple of 778,246,128,670,819 is 560108465280.

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.

778 x 246 x 128 x 670 x 819 = 13442603166720

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.

778 : 1, 2, 389, 778

246 : 1, 2, 3, 6, 41, 82, 123, 246

128 : 1, 2, 4, 8, 16, 32, 64, 128

670 : 1, 2, 5, 10, 67, 134, 335, 670

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,246,128,670,819, is 1.

Now, the common factors can be found like this.

778:2x 389

246:2x 3x 41

128:2x 2x 2x 2x 2x 2x 2

670:2x 5x 67

819:3x 3x 7x 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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 13442603166720/(1x24)

LCM = 13442603166720/24

LCM = 560108465280

Thus, we can understand that the LCM of 778,246,128,670,819 is 560108465280.
