Given numbers are 676,845,621,409

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

The LCM of 676,845,621,409 is 858482820.

Find LCM of 676,845,621,409 with Prime Factorization

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

13 x 13 x 4 x 5 x 621 x 409 = 858482820

Therefore, the lowest common multiple of 676,845,621,409 is 858482820.

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.

676 x 845 x 621 x 409 = 145083596580

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.

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

845 : 1, 5, 13, 65, 169, 845

621 : 1, 3, 9, 23, 27, 69, 207, 621

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,845,621,409, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

845:5x 13x 13

621:3x 3x 3x 23

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.

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 145083596580/(1x169)

LCM = 145083596580/169

LCM = 858482820

Thus, we can understand that the LCM of 676,845,621,409 is 858482820.
