Given numbers are 919,556,172,393

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

The LCM of 919,556,172,393 is 8634780636.

Find LCM of 919,556,172,393 with Prime Factorization

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

2 x 2 x 919 x 139 x 43 x 393 = 8634780636

Therefore, the lowest common multiple of 919,556,172,393 is 8634780636.

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.

919 x 556 x 172 x 393 = 34539122544

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.

919 : 1, 919

556 : 1, 2, 4, 139, 278, 556

172 : 1, 2, 4, 43, 86, 172

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,556,172,393, is 1.

Now, the common factors can be found like this.

919:919

556:2x 2x 139

172:2x 2x 43

393:3x 131

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 34539122544/(1x4)

LCM = 34539122544/4

LCM = 8634780636

Thus, we can understand that the LCM of 919,556,172,393 is 8634780636.
