Given numbers are 440,395,856,440

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

The LCM of 440,395,856,440 is 3719320.

Find LCM of 440,395,856,440 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 79 x 107 x 1 = 3719320

Therefore, the lowest common multiple of 440,395,856,440 is 3719320.

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 395 x 856 x 440 = 65460032000

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

395 : 1, 5, 79, 395

856 : 1, 2, 4, 8, 107, 214, 428, 856

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,395,856,440, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

395:5x 79

856:2x 2x 2x 107

440:2x 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 2x 5x 5x 11 = 17600

Therefore, the value for common factors is 17600.

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 = 65460032000/(1x17600)

LCM = 65460032000/17600

LCM = 3719320

Thus, we can understand that the LCM of 440,395,856,440 is 3719320.
