Given numbers are 409,286,668,357

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

The LCM of 409,286,668,357 is 13947745812.

Find LCM of 409,286,668,357 with Prime Factorization

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

2 x 409 x 143 x 334 x 357 = 13947745812

Therefore, the lowest common multiple of 409,286,668,357 is 13947745812.

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.

409 x 286 x 668 x 357 = 27895491624

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.

409 : 1, 409

286 : 1, 2, 11, 13, 22, 26, 143, 286

668 : 1, 2, 4, 167, 334, 668

357 : 1, 3, 7, 17, 21, 51, 119, 357

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,286,668,357, is 1.

Now, the common factors can be found like this.

409:409

286:2x 11x 13

668:2x 2x 167

357:3x 7x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 27895491624/(1x2)

LCM = 27895491624/2

LCM = 13947745812

Thus, we can understand that the LCM of 409,286,668,357 is 13947745812.
