Given numbers are 440,828,647,880

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

The LCM of 440,828,647,880 is 117857520.

Find LCM of 440,828,647,880 with Prime Factorization

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

2 x 2 x 2 x 5 x 11 x 1 x 207 x 647 x 2 = 117857520

Therefore, the lowest common multiple of 440,828,647,880 is 117857520.

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.

440 x 828 x 647 x 880 = 207429235200

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.

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

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

647 : 1, 647

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 440,828,647,880, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

828:2x 2x 3x 3x 23

647:647

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 11 = 1760

Therefore, the value for common factors is 1760.

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 = 207429235200/(1x1760)

LCM = 207429235200/1760

LCM = 117857520

Thus, we can understand that the LCM of 440,828,647,880 is 117857520.
