Given numbers are 396,493,170,641

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

The LCM of 396,493,170,641 is 625705740.

Find LCM of 396,493,170,641 with Prime Factorization

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

2 x 17 x 198 x 29 x 5 x 641 = 625705740

Therefore, the lowest common multiple of 396,493,170,641 is 625705740.

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.

396 x 493 x 170 x 641 = 21273995160

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.

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

493 : 1, 17, 29, 493

170 : 1, 2, 5, 10, 17, 34, 85, 170

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,493,170,641, is 1.

Now, the common factors can be found like this.

396:2x 2x 3x 3x 11

493:17x 29

170:2x 5x 17

641:641

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 21273995160/(1x34)

LCM = 21273995160/34

LCM = 625705740

Thus, we can understand that the LCM of 396,493,170,641 is 625705740.
