Given numbers are 647,839,228,418,394

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

The LCM of 647,839,228,418,394 is 268200757308.

Find LCM of 647,839,228,418,394 with Prime Factorization

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

2 x 19 x 647 x 839 x 6 x 11 x 197 = 268200757308

Therefore, the lowest common multiple of 647,839,228,418,394 is 268200757308.

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.

647 x 839 x 228 x 418 x 394 = 20383257555408

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.

647 : 1, 647

839 : 1, 839

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

418 : 1, 2, 11, 19, 22, 38, 209, 418

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,839,228,418,394, is 1.

Now, the common factors can be found like this.

647:647

839:839

228:2x 2x 3x 19

418:2x 11x 19

394:2x 197

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

2x 2x 19 = 76

Therefore, the value for common factors is 76.

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 = 20383257555408/(1x76)

LCM = 20383257555408/76

LCM = 268200757308

Thus, we can understand that the LCM of 647,839,228,418,394 is 268200757308.
