Given numbers are 340,638,181,209

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

The LCM of 340,638,181,209 is 372993940.

Find LCM of 340,638,181,209 with Prime Factorization

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

2 x 11 x 170 x 29 x 181 x 19 = 372993940

Therefore, the lowest common multiple of 340,638,181,209 is 372993940.

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.

340 x 638 x 181 x 209 = 8205866680

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.

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

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

181 : 1, 181

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,638,181,209, is 1.

Now, the common factors can be found like this.

340:2x 2x 5x 17

638:2x 11x 29

181:181

209:11x 19

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 8205866680/(1x22)

LCM = 8205866680/22

LCM = 372993940

Thus, we can understand that the LCM of 340,638,181,209 is 372993940.
