Given numbers are 864,209,649,821,673

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

The LCM of 864,209,649,821,673 is 5886677741472.

Find LCM of 864,209,649,821,673 with Prime Factorization

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

11 x 864 x 19 x 59 x 821 x 673 = 5886677741472

Therefore, the lowest common multiple of 864,209,649,821,673 is 5886677741472.

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.

864 x 209 x 649 x 821 x 673 = 64753455156192

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.

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

209 : 1, 11, 19, 209

649 : 1, 11, 59, 649

821 : 1, 821

673 : 1, 673

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,209,649,821,673, is 1.

Now, the common factors can be found like this.

864:2x 2x 2x 2x 2x 3x 3x 3

209:11x 19

649:11x 59

821:821

673:673

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

11 = 11

Therefore, the value for common factors is 11.

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 = 64753455156192/(1x11)

LCM = 64753455156192/11

LCM = 5886677741472

Thus, we can understand that the LCM of 864,209,649,821,673 is 5886677741472.
