Given numbers are 391,910,299,247

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

The LCM of 391,910,299,247 is 6760390.

Find LCM of 391,910,299,247 with Prime Factorization

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

13 x 23 x 17 x 70 x 1 x 19 = 6760390

Therefore, the lowest common multiple of 391,910,299,247 is 6760390.

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.

391 x 910 x 299 x 247 = 26277635930

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.

391 : 1, 17, 23, 391

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

299 : 1, 13, 23, 299

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,910,299,247, is 1.

Now, the common factors can be found like this.

391:17x 23

910:2x 5x 7x 13

299:13x 23

247:13x 19

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

13x 13x 23 = 3887

Therefore, the value for common factors is 3887.

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 = 26277635930/(1x3887)

LCM = 26277635930/3887

LCM = 6760390

Thus, we can understand that the LCM of 391,910,299,247 is 6760390.
