Given numbers are 105,389,620,199,381

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

The LCM of 105,389,620,199,381 is 128002184940.

Find LCM of 105,389,620,199,381 with Prime Factorization

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

3 x 5 x 7 x 389 x 124 x 199 x 127 = 128002184940

Therefore, the lowest common multiple of 105,389,620,199,381 is 128002184940.

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.

105 x 389 x 620 x 199 x 381 = 1920032774100

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.

105 : 1, 3, 5, 7, 15, 21, 35, 105

389 : 1, 389

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

199 : 1, 199

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,389,620,199,381, is 1.

Now, the common factors can be found like this.

105:3x 5x 7

389:389

620:2x 2x 5x 31

199:199

381:3x 127

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 1920032774100/(1x15)

LCM = 1920032774100/15

LCM = 128002184940

Thus, we can understand that the LCM of 105,389,620,199,381 is 128002184940.
