Given numbers are 394,323,990,880

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

The LCM of 394,323,990,880 is 503957520.

Find LCM of 394,323,990,880 with Prime Factorization

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

2 x 5 x 11 x 197 x 323 x 9 x 8 = 503957520

Therefore, the lowest common multiple of 394,323,990,880 is 503957520.

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.

394 x 323 x 990 x 880 = 110870654400

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.

394 : 1, 2, 197, 394

323 : 1, 17, 19, 323

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

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 394,323,990,880, is 1.

Now, the common factors can be found like this.

394:2x 197

323:17x 19

990:2x 3x 3x 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 5x 11 = 220

Therefore, the value for common factors is 220.

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 = 110870654400/(1x220)

LCM = 110870654400/220

LCM = 503957520

Thus, we can understand that the LCM of 394,323,990,880 is 503957520.
