Given numbers are 818,847,687,409

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

The LCM of 818,847,687,409 is 475985202.

Find LCM of 818,847,687,409 with Prime Factorization

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

409 x 2 x 847 x 687 x 1 = 475985202

Therefore, the lowest common multiple of 818,847,687,409 is 475985202.

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 847 x 687 x 409 = 194677947618

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

847 : 1, 7, 11, 77, 121, 847

687 : 1, 3, 229, 687

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,847,687,409, is 1.

Now, the common factors can be found like this.

818:2x 409

847:7x 11x 11

687:3x 229

409:409

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 = 194677947618/(1x409)

LCM = 194677947618/409

LCM = 475985202

Thus, we can understand that the LCM of 818,847,687,409 is 475985202.
