Given numbers are 979,817,660,440,880

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

The LCM of 979,817,660,440,880 is 191962320.

Find LCM of 979,817,660,440,880 with Prime Factorization

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

2 x 2 x 2 x 5 x 11 x 89 x 817 x 3 x 1 x 2 = 191962320

Therefore, the lowest common multiple of 979,817,660,440,880 is 191962320.

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.

979 x 817 x 660 x 440 x 880 = 204401478336000

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.

979 : 1, 11, 89, 979

817 : 1, 19, 43, 817

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,817,660,440,880, is 1.

Now, the common factors can be found like this.

979:11x 89

817:19x 43

660:2x 2x 3x 5x 11

440:2x 2x 2x 5x 11

880:2x 2x 2x 2x 5x 11

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 2x 2x 5x 5x 11x 11x 11 = 1064800

Therefore, the value for common factors is 1064800.

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 = 204401478336000/(1x1064800)

LCM = 204401478336000/1064800

LCM = 191962320

Thus, we can understand that the LCM of 979,817,660,440,880 is 191962320.
