Given numbers are 521,990,278,841

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

The LCM of 521,990,278,841 is 60295335210.

Find LCM of 521,990,278,841 with Prime Factorization

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

2 x 521 x 495 x 139 x 841 = 60295335210

Therefore, the lowest common multiple of 521,990,278,841 is 60295335210.

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.

521 x 990 x 278 x 841 = 120590670420

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.

521 : 1, 521

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

278 : 1, 2, 139, 278

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,990,278,841, is 1.

Now, the common factors can be found like this.

521:521

990:2x 3x 3x 5x 11

278:2x 139

841:29x 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 = 120590670420/(1x2)

LCM = 120590670420/2

LCM = 60295335210

Thus, we can understand that the LCM of 521,990,278,841 is 60295335210.
