Given numbers are 447,220,880,380

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

The LCM of 447,220,880,380 is 7473840.

Find LCM of 447,220,880,380 with Prime Factorization

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

2 x 2 x 5 x 11 x 447 x 1 x 4 x 19 = 7473840

Therefore, the lowest common multiple of 447,220,880,380 is 7473840.

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.

447 x 220 x 880 x 380 = 32884896000

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.

447 : 1, 3, 149, 447

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

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

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,220,880,380, is 1.

Now, the common factors can be found like this.

447:3x 149

220:2x 2x 5x 11

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

380:2x 2x 5x 19

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 5x 5x 11 = 4400

Therefore, the value for common factors is 4400.

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 = 32884896000/(1x4400)

LCM = 32884896000/4400

LCM = 7473840

Thus, we can understand that the LCM of 447,220,880,380 is 7473840.
