Given numbers are 818,580,381,197

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

The LCM of 818,580,381,197 is 17805021540.

Find LCM of 818,580,381,197 with Prime Factorization

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

2 x 409 x 290 x 381 x 197 = 17805021540

Therefore, the lowest common multiple of 818,580,381,197 is 17805021540.

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 580 x 381 x 197 = 35610043080

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

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

381 : 1, 3, 127, 381

197 : 1, 197

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,580,381,197, is 1.

Now, the common factors can be found like this.

818:2x 409

580:2x 2x 5x 29

381:3x 127

197:197

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 = 35610043080/(1x2)

LCM = 35610043080/2

LCM = 17805021540

Thus, we can understand that the LCM of 818,580,381,197 is 17805021540.
