Given numbers are 818,585,409,649

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

The LCM of 818,585,409,649 is 310565970.

Find LCM of 818,585,409,649 with Prime Factorization

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

409 x 2 x 585 x 1 x 649 = 310565970

Therefore, the lowest common multiple of 818,585,409,649 is 310565970.

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.

818 x 585 x 409 x 649 = 127021481730

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.

818 : 1, 2, 409, 818

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

409 : 1, 409

649 : 1, 11, 59, 649

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,585,409,649, is 1.

Now, the common factors can be found like this.

818:2x 409

585:3x 3x 5x 13

409:409

649:11x 59

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

409 = 409

Therefore, the value for common factors is 409.

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 = 127021481730/(1x409)

LCM = 127021481730/409

LCM = 310565970

Thus, we can understand that the LCM of 818,585,409,649 is 310565970.
