Given numbers are 311,492,319,128

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

The LCM of 311,492,319,128 is 1561946496.

Find LCM of 311,492,319,128 with Prime Factorization

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

2 x 2 x 311 x 123 x 319 x 32 = 1561946496

Therefore, the lowest common multiple of 311,492,319,128 is 1561946496.

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 492 x 319 x 128 = 6247785984

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

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

319 : 1, 11, 29, 319

128 : 1, 2, 4, 8, 16, 32, 64, 128

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,492,319,128, is 1.

Now, the common factors can be found like this.

311:311

492:2x 2x 3x 41

319:11x 29

128:2x 2x 2x 2x 2x 2x 2

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 = 6247785984/(1x4)

LCM = 6247785984/4

LCM = 1561946496

Thus, we can understand that the LCM of 311,492,319,128 is 1561946496.
