Given numbers are 638,437,486,958,161

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

The LCM of 638,437,486,958,161 is 227165273874.

Find LCM of 638,437,486,958,161 with Prime Factorization

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

2 x 23 x 319 x 19 x 243 x 479 x 7 = 227165273874

Therefore, the lowest common multiple of 638,437,486,958,161 is 227165273874.

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.

638 x 437 x 486 x 958 x 161 = 20899205196408

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.

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

437 : 1, 19, 23, 437

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

958 : 1, 2, 479, 958

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,437,486,958,161, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

437:19x 23

486:2x 3x 3x 3x 3x 3

958:2x 479

161:7x 23

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

2x 2x 23 = 92

Therefore, the value for common factors is 92.

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 = 20899205196408/(1x92)

LCM = 20899205196408/92

LCM = 227165273874

Thus, we can understand that the LCM of 638,437,486,958,161 is 227165273874.
