Given numbers are 838,194,438,838,209

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

The LCM of 838,194,438,838,209 is 3720541506.

Find LCM of 838,194,438,838,209 with Prime Factorization

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

2 x 419 x 1 x 97 x 219 x 1 x 209 = 3720541506

Therefore, the lowest common multiple of 838,194,438,838,209 is 3720541506.

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.

838 x 194 x 438 x 838 x 209 = 12471255128112

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.

838 : 1, 2, 419, 838

194 : 1, 2, 97, 194

438 : 1, 2, 3, 6, 73, 146, 219, 438

838 : 1, 2, 419, 838

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,194,438,838,209, is 1.

Now, the common factors can be found like this.

838:2x 419

194:2x 97

438:2x 3x 73

838:2x 419

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 2x 2x 419 = 3352

Therefore, the value for common factors is 3352.

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 = 12471255128112/(1x3352)

LCM = 12471255128112/3352

LCM = 3720541506

Thus, we can understand that the LCM of 838,194,438,838,209 is 3720541506.
