Given numbers are 409,637,247,338

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

The LCM of 409,637,247,338 is 128703302.

Find LCM of 409,637,247,338 with Prime Factorization

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

13 x 409 x 49 x 19 x 26 = 128703302

Therefore, the lowest common multiple of 409,637,247,338 is 128703302.

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 637 x 247 x 338 = 21750858038

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

637 : 1, 7, 13, 49, 91, 637

247 : 1, 13, 19, 247

338 : 1, 2, 13, 26, 169, 338

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,637,247,338, is 1.

Now, the common factors can be found like this.

409:409

637:7x 7x 13

247:13x 19

338:2x 13x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 21750858038/(1x169)

LCM = 21750858038/169

LCM = 128703302

Thus, we can understand that the LCM of 409,637,247,338 is 128703302.
