Given numbers are 856,351,793,431

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

The LCM of 856,351,793,431 is 7899288696.

Find LCM of 856,351,793,431 with Prime Factorization

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

13 x 856 x 27 x 61 x 431 = 7899288696

Therefore, the lowest common multiple of 856,351,793,431 is 7899288696.

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.

856 x 351 x 793 x 431 = 102690753048

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

351 : 1, 3, 9, 13, 27, 39, 117, 351

793 : 1, 13, 61, 793

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,351,793,431, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

351:3x 3x 3x 13

793:13x 61

431:431

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

13 = 13

Therefore, the value for common factors is 13.

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 = 102690753048/(1x13)

LCM = 102690753048/13

LCM = 7899288696

Thus, we can understand that the LCM of 856,351,793,431 is 7899288696.
