Given numbers are 193,778,138,851

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

The LCM of 193,778,138,851 is 383343162.

Find LCM of 193,778,138,851 with Prime Factorization

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

2 x 23 x 193 x 389 x 3 x 37 = 383343162

Therefore, the lowest common multiple of 193,778,138,851 is 383343162.

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.

193 x 778 x 138 x 851 = 17633785452

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.

193 : 1, 193

778 : 1, 2, 389, 778

138 : 1, 2, 3, 6, 23, 46, 69, 138

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,778,138,851, is 1.

Now, the common factors can be found like this.

193:193

778:2x 389

138:2x 3x 23

851:23x 37

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 17633785452/(1x46)

LCM = 17633785452/46

LCM = 383343162

Thus, we can understand that the LCM of 193,778,138,851 is 383343162.
