Given numbers are 108,770,272,539,781

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

The LCM of 108,770,272,539,781 is 1405237680.

Find LCM of 108,770,272,539,781 with Prime Factorization

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

2 x 2 x 7 x 11 x 27 x 5 x 68 x 7 x 71 = 1405237680

Therefore, the lowest common multiple of 108,770,272,539,781 is 1405237680.

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.

108 x 770 x 272 x 539 x 781 = 9521890519680

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.

108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

539 : 1, 7, 11, 49, 77, 539

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 108,770,272,539,781, is 1.

Now, the common factors can be found like this.

108:2x 2x 3x 3x 3

770:2x 5x 7x 11

272:2x 2x 2x 2x 17

539:7x 7x 11

781:11x 71

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

2x 2x 2x 7x 11x 11 = 6776

Therefore, the value for common factors is 6776.

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 = 9521890519680/(1x6776)

LCM = 9521890519680/6776

LCM = 1405237680

Thus, we can understand that the LCM of 108,770,272,539,781 is 1405237680.
