Given numbers are 834,781,568,821

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

The LCM of 834,781,568,821 is 2139046536.

Find LCM of 834,781,568,821 with Prime Factorization

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

2 x 71 x 417 x 11 x 4 x 821 = 2139046536

Therefore, the lowest common multiple of 834,781,568,821 is 2139046536.

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.

834 x 781 x 568 x 821 = 303744608112

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.

834 : 1, 2, 3, 6, 139, 278, 417, 834

781 : 1, 11, 71, 781

568 : 1, 2, 4, 8, 71, 142, 284, 568

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,781,568,821, is 1.

Now, the common factors can be found like this.

834:2x 3x 139

781:11x 71

568:2x 2x 2x 71

821:821

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 303744608112/(1x142)

LCM = 303744608112/142

LCM = 2139046536

Thus, we can understand that the LCM of 834,781,568,821 is 2139046536.
