Given numbers are 349,861,323,646

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

The LCM of 349,861,323,646 is 194115894.

Find LCM of 349,861,323,646 with Prime Factorization

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

17 x 19 x 349 x 861 x 1 x 2 = 194115894

Therefore, the lowest common multiple of 349,861,323,646 is 194115894.

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.

349 x 861 x 323 x 646 = 62699433762

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.

349 : 1, 349

861 : 1, 3, 7, 21, 41, 123, 287, 861

323 : 1, 17, 19, 323

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 349,861,323,646, is 1.

Now, the common factors can be found like this.

349:349

861:3x 7x 41

323:17x 19

646:2x 17x 19

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

17x 19 = 323

Therefore, the value for common factors is 323.

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 = 62699433762/(1x323)

LCM = 62699433762/323

LCM = 194115894

Thus, we can understand that the LCM of 349,861,323,646 is 194115894.
