Given numbers are 919,643,556,668

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

The LCM of 919,643,556,668 is 54867825284.

Find LCM of 919,643,556,668 with Prime Factorization

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

2 x 2 x 919 x 643 x 139 x 167 = 54867825284

Therefore, the lowest common multiple of 919,643,556,668 is 54867825284.

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 643 x 556 x 668 = 219471301136

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

643 : 1, 643

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

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,643,556,668, is 1.

Now, the common factors can be found like this.

919:919

643:643

556:2x 2x 139

668:2x 2x 167

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 = 219471301136/(1x4)

LCM = 219471301136/4

LCM = 54867825284

Thus, we can understand that the LCM of 919,643,556,668 is 54867825284.
