Given numbers are 423,265,646,386

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

The LCM of 423,265,646,386 is 13975780410.

Find LCM of 423,265,646,386 with Prime Factorization

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

2 x 423 x 265 x 323 x 193 = 13975780410

Therefore, the lowest common multiple of 423,265,646,386 is 13975780410.

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.

423 x 265 x 646 x 386 = 27951560820

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.

423 : 1, 3, 9, 47, 141, 423

265 : 1, 5, 53, 265

646 : 1, 2, 17, 19, 34, 38, 323, 646

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,265,646,386, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

265:5x 53

646:2x 17x 19

386:2x 193

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 = 27951560820/(1x2)

LCM = 27951560820/2

LCM = 13975780410

Thus, we can understand that the LCM of 423,265,646,386 is 13975780410.
