Given numbers are 830,840,778,206

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

The LCM of 830,840,778,206 is 2793471240.

Find LCM of 830,840,778,206 with Prime Factorization

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

2 x 5 x 83 x 84 x 389 x 103 = 2793471240

Therefore, the lowest common multiple of 830,840,778,206 is 2793471240.

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.

830 x 840 x 778 x 206 = 111738849600

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.

830 : 1, 2, 5, 10, 83, 166, 415, 830

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

778 : 1, 2, 389, 778

206 : 1, 2, 103, 206

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,840,778,206, is 2.

Now, the common factors can be found like this.

830:2x 5x 83

840:2x 2x 2x 3x 5x 7

778:2x 389

206:2x 103

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 5 = 20

Therefore, the value for common factors is 20.

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 = 111738849600/(2x20)

LCM = 111738849600/40

LCM = 2793471240

Thus, we can understand that the LCM of 830,840,778,206 is 2793471240.
