Given numbers are 821,853,489,489,554

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

The LCM of 821,853,489,489,554 is 189718993578.

Find LCM of 821,853,489,489,554 with Prime Factorization

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

3 x 163 x 821 x 853 x 1 x 1 x 554 = 189718993578

Therefore, the lowest common multiple of 821,853,489,489,554 is 189718993578.

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 853 x 489 x 489 x 554 = 92772587859642

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

853 : 1, 853

489 : 1, 3, 163, 489

489 : 1, 3, 163, 489

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,853,489,489,554, is 1.

Now, the common factors can be found like this.

821:821

853:853

489:3x 163

489:3x 163

554:2x 277

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

3x 163 = 489

Therefore, the value for common factors is 489.

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 = 92772587859642/(1x489)

LCM = 92772587859642/489

LCM = 189718993578

Thus, we can understand that the LCM of 821,853,489,489,554 is 189718993578.
