Given numbers are 821,647,466,284

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

The LCM of 821,647,466,284 is 35149706164.

Find LCM of 821,647,466,284 with Prime Factorization

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

2 x 821 x 647 x 233 x 142 = 35149706164

Therefore, the lowest common multiple of 821,647,466,284 is 35149706164.

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 647 x 466 x 284 = 70299412328

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

647 : 1, 647

466 : 1, 2, 233, 466

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,647,466,284, is 1.

Now, the common factors can be found like this.

821:821

647:647

466:2x 233

284:2x 2x 71

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 = 70299412328/(1x2)

LCM = 70299412328/2

LCM = 35149706164

Thus, we can understand that the LCM of 821,647,466,284 is 35149706164.
