Given numbers are 409,266,418,354

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

The LCM of 409,266,418,354 is 211821918.

Find LCM of 409,266,418,354 with Prime Factorization

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

2 x 19 x 409 x 7 x 11 x 177 = 211821918

Therefore, the lowest common multiple of 409,266,418,354 is 211821918.

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 266 x 418 x 354 = 16098465768

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

266 : 1, 2, 7, 14, 19, 38, 133, 266

418 : 1, 2, 11, 19, 22, 38, 209, 418

354 : 1, 2, 3, 6, 59, 118, 177, 354

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,266,418,354, is 1.

Now, the common factors can be found like this.

409:409

266:2x 7x 19

418:2x 11x 19

354:2x 3x 59

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 19 = 76

Therefore, the value for common factors is 76.

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 = 16098465768/(1x76)

LCM = 16098465768/76

LCM = 211821918

Thus, we can understand that the LCM of 409,266,418,354 is 211821918.
