Given numbers are 991,277,391,391

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

The LCM of 991,277,391,391 is 107332237.

Find LCM of 991,277,391,391 with Prime Factorization

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

17 x 23 x 991 x 277 x 1 x 1 = 107332237

Therefore, the lowest common multiple of 991,277,391,391 is 107332237.

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.

991 x 277 x 391 x 391 = 41966904667

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.

991 : 1, 991

277 : 1, 277

391 : 1, 17, 23, 391

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,277,391,391, is 1.

Now, the common factors can be found like this.

991:991

277:277

391:17x 23

391:17x 23

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

17x 23 = 391

Therefore, the value for common factors is 391.

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 = 41966904667/(1x391)

LCM = 41966904667/391

LCM = 107332237

Thus, we can understand that the LCM of 991,277,391,391 is 107332237.
