Given numbers are 311,638,239,717

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

The LCM of 311,638,239,717 is 142265706.

Find LCM of 311,638,239,717 with Prime Factorization

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

239 x 311 x 638 x 1 x 3 = 142265706

Therefore, the lowest common multiple of 311,638,239,717 is 142265706.

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.

311 x 638 x 239 x 717 = 34001503734

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.

311 : 1, 311

638 : 1, 2, 11, 22, 29, 58, 319, 638

239 : 1, 239

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,638,239,717, is 1.

Now, the common factors can be found like this.

311:311

638:2x 11x 29

239:239

717:3x 239

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

239 = 239

Therefore, the value for common factors is 239.

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 = 34001503734/(1x239)

LCM = 34001503734/239

LCM = 142265706

Thus, we can understand that the LCM of 311,638,239,717 is 142265706.
