Given numbers are 343,326,815,621

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

The LCM of 343,326,815,621 is 347194890.

Find LCM of 343,326,815,621 with Prime Factorization

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

163 x 343 x 2 x 5 x 621 = 347194890

Therefore, the lowest common multiple of 343,326,815,621 is 347194890.

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.

343 x 326 x 815 x 621 = 56592767070

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.

343 : 1, 7, 49, 343

326 : 1, 2, 163, 326

815 : 1, 5, 163, 815

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,326,815,621, is 1.

Now, the common factors can be found like this.

343:7x 7x 7

326:2x 163

815:5x 163

621:3x 3x 3x 23

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

163 = 163

Therefore, the value for common factors is 163.

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 = 56592767070/(1x163)

LCM = 56592767070/163

LCM = 347194890

Thus, we can understand that the LCM of 343,326,815,621 is 347194890.
