Given numbers are 409,830,821,734

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

The LCM of 409,830,821,734 is 102284687290.

Find LCM of 409,830,821,734 with Prime Factorization

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

2 x 409 x 415 x 821 x 367 = 102284687290

Therefore, the lowest common multiple of 409,830,821,734 is 102284687290.

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.

409 x 830 x 821 x 734 = 204569374580

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.

409 : 1, 409

830 : 1, 2, 5, 10, 83, 166, 415, 830

821 : 1, 821

734 : 1, 2, 367, 734

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,830,821,734, is 1.

Now, the common factors can be found like this.

409:409

830:2x 5x 83

821:821

734:2x 367

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 = 204569374580/(1x2)

LCM = 204569374580/2

LCM = 102284687290

Thus, we can understand that the LCM of 409,830,821,734 is 102284687290.
