Given numbers are 794,172,390

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

The LCM of 794,172,390 is 13315380.

Find LCM of 794,172,390 with Prime Factorization

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

2 x 397 x 86 x 195 = 13315380

Therefore, the lowest common multiple of 794,172,390 is 13315380.

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.

794 x 172 x 390 = 53261520

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.

794 : 1, 2, 397, 794

172 : 1, 2, 4, 43, 86, 172

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 794,172,390, is 2.

Now, the common factors can be found like this.

794:2x 397

172:2x 2x 43

390:2x 3x 5x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 53261520/(2x2)

LCM = 53261520/4

LCM = 13315380

Thus, we can understand that the LCM of 794,172,390 is 13315380.
