Given numbers are 242,386,686,861,416

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

The LCM of 242,386,686,861,416 is 409859722272.

Find LCM of 242,386,686,861,416 with Prime Factorization

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

2 x 7 x 121 x 193 x 49 x 123 x 208 = 409859722272

Therefore, the lowest common multiple of 242,386,686,861,416 is 409859722272.

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.

242 x 386 x 686 x 861 x 416 = 22952144447232

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.

242 : 1, 2, 11, 22, 121, 242

386 : 1, 2, 193, 386

686 : 1, 2, 7, 14, 49, 98, 343, 686

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

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,386,686,861,416, is 1.

Now, the common factors can be found like this.

242:2x 11x 11

386:2x 193

686:2x 7x 7x 7

861:3x 7x 41

416:2x 2x 2x 2x 2x 13

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 2x 7 = 56

Therefore, the value for common factors is 56.

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 = 22952144447232/(1x56)

LCM = 22952144447232/56

LCM = 409859722272

Thus, we can understand that the LCM of 242,386,686,861,416 is 409859722272.
