Given numbers are 390,936,851,923,193

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

The LCM of 390,936,851,923,193 is 54574664040.

Find LCM of 390,936,851,923,193 with Prime Factorization

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

2 x 3 x 13 x 5 x 12 x 851 x 71 x 193 = 54574664040

Therefore, the lowest common multiple of 390,936,851,923,193 is 54574664040.

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.

390 x 936 x 851 x 923 x 193 = 55338709336560

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

851 : 1, 23, 37, 851

923 : 1, 13, 71, 923

193 : 1, 193

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,936,851,923,193, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

936:2x 2x 2x 3x 3x 13

851:23x 37

923:13x 71

193:193

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

2x 3x 13x 13 = 1014

Therefore, the value for common factors is 1014.

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 = 55338709336560/(1x1014)

LCM = 55338709336560/1014

LCM = 54574664040

Thus, we can understand that the LCM of 390,936,851,923,193 is 54574664040.
