Given numbers are 391,897,497,253

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

The LCM of 391,897,497,253 is 83366283.

Find LCM of 391,897,497,253 with Prime Factorization

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

23 x 17 x 39 x 497 x 11 = 83366283

Therefore, the lowest common multiple of 391,897,497,253 is 83366283.

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 897 x 497 x 253 = 44100763707

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

897 : 1, 3, 13, 23, 39, 69, 299, 897

497 : 1, 7, 71, 497

253 : 1, 11, 23, 253

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,897,497,253, is 1.

Now, the common factors can be found like this.

391:17x 23

897:3x 13x 23

497:7x 71

253:11x 23

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

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 44100763707/(1x529)

LCM = 44100763707/529

LCM = 83366283

Thus, we can understand that the LCM of 391,897,497,253 is 83366283.
