Given numbers are 209,171,794,397

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

The LCM of 209,171,794,397 is 1493514.

Find LCM of 209,171,794,397 with Prime Factorization

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

19 x 397 x 11 x 9 x 2 x 1 = 1493514

Therefore, the lowest common multiple of 209,171,794,397 is 1493514.

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.

209 x 171 x 794 x 397 = 11265576102

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.

209 : 1, 11, 19, 209

171 : 1, 3, 9, 19, 57, 171

794 : 1, 2, 397, 794

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,171,794,397, is 1.

Now, the common factors can be found like this.

209:11x 19

171:3x 3x 19

794:2x 397

397:397

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

19x 397 = 7543

Therefore, the value for common factors is 7543.

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 = 11265576102/(1x7543)

LCM = 11265576102/7543

LCM = 1493514

Thus, we can understand that the LCM of 209,171,794,397 is 1493514.
