Given numbers are 346,642,364,821

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

The LCM of 346,642,364,821 is 16595703852.

Find LCM of 346,642,364,821 with Prime Factorization

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

2 x 173 x 321 x 182 x 821 = 16595703852

Therefore, the lowest common multiple of 346,642,364,821 is 16595703852.

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.

346 x 642 x 364 x 821 = 66382815408

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.

346 : 1, 2, 173, 346

642 : 1, 2, 3, 6, 107, 214, 321, 642

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 346,642,364,821, is 1.

Now, the common factors can be found like this.

346:2x 173

642:2x 3x 107

364:2x 2x 7x 13

821:821

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 66382815408/(1x4)

LCM = 66382815408/4

LCM = 16595703852

Thus, we can understand that the LCM of 346,642,364,821 is 16595703852.
