Given numbers are 821,197,834,805,754

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

The LCM of 821,197,834,805,754 is 40936684373130.

Find LCM of 821,197,834,805,754 with Prime Factorization

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

2 x 821 x 197 x 417 x 805 x 377 = 40936684373130

Therefore, the lowest common multiple of 821,197,834,805,754 is 40936684373130.

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.

821 x 197 x 834 x 805 x 754 = 81873368746260

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.

821 : 1, 821

197 : 1, 197

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

805 : 1, 5, 7, 23, 35, 115, 161, 805

754 : 1, 2, 13, 26, 29, 58, 377, 754

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,197,834,805,754, is 1.

Now, the common factors can be found like this.

821:821

197:197

834:2x 3x 139

805:5x 7x 23

754:2x 13x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 81873368746260/(1x2)

LCM = 81873368746260/2

LCM = 40936684373130

Thus, we can understand that the LCM of 821,197,834,805,754 is 40936684373130.
