Given numbers are 685,422,366,638

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

The LCM of 685,422,366,638 is 16875039390.

Find LCM of 685,422,366,638 with Prime Factorization

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

2 x 685 x 211 x 183 x 319 = 16875039390

Therefore, the lowest common multiple of 685,422,366,638 is 16875039390.

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.

685 x 422 x 366 x 638 = 67500157560

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.

685 : 1, 5, 137, 685

422 : 1, 2, 211, 422

366 : 1, 2, 3, 6, 61, 122, 183, 366

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,422,366,638, is 1.

Now, the common factors can be found like this.

685:5x 137

422:2x 211

366:2x 3x 61

638:2x 11x 29

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 = 67500157560/(1x4)

LCM = 67500157560/4

LCM = 16875039390

Thus, we can understand that the LCM of 685,422,366,638 is 16875039390.
