Given numbers are 1,988,247,313

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

The LCM of 1,988,247,313 is 309244.

Find LCM of 1,988,247,313 with Prime Factorization

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

13 x 19 x 1 x 4 x 1 x 313 = 309244

Therefore, the lowest common multiple of 1,988,247,313 is 309244.

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.

1 x 988 x 247 x 313 = 76383268

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.

1 : 1

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

247 : 1, 13, 19, 247

313 : 1, 313

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,988,247,313, is 1.

Now, the common factors can be found like this.

1:

988:2x 2x 13x 19

247:13x 19

313:313

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

13x 19 = 247

Therefore, the value for common factors is 247.

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 = 76383268/(1x247)

LCM = 76383268/247

LCM = 309244

Thus, we can understand that the LCM of 1,988,247,313 is 309244.
