Given numbers are 990,186,681,618,841

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

The LCM of 990,186,681,618,841 is 603470390490.

Find LCM of 990,186,681,618,841 with Prime Factorization

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

2 x 3 x 165 x 31 x 227 x 103 x 841 = 603470390490

Therefore, the lowest common multiple of 990,186,681,618,841 is 603470390490.

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.

990 x 186 x 681 x 618 x 841 = 65174802172920

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.

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

186 : 1, 2, 3, 6, 31, 62, 93, 186

681 : 1, 3, 227, 681

618 : 1, 2, 3, 6, 103, 206, 309, 618

841 : 1, 29, 841

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,186,681,618,841, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

186:2x 3x 31

681:3x 227

618:2x 3x 103

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.

2x 2x 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 65174802172920/(1x108)

LCM = 65174802172920/108

LCM = 603470390490

Thus, we can understand that the LCM of 990,186,681,618,841 is 603470390490.
