Given numbers are 840,886,778,853

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

The LCM of 840,886,778,853 is 123475742040.

Find LCM of 840,886,778,853 with Prime Factorization

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

2 x 420 x 443 x 389 x 853 = 123475742040

Therefore, the lowest common multiple of 840,886,778,853 is 123475742040.

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.

840 x 886 x 778 x 853 = 493902968160

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.

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

886 : 1, 2, 443, 886

778 : 1, 2, 389, 778

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,886,778,853, is 1.

Now, the common factors can be found like this.

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

886:2x 443

778:2x 389

853:853

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 493902968160/(1x4)

LCM = 493902968160/4

LCM = 123475742040

Thus, we can understand that the LCM of 840,886,778,853 is 123475742040.
