Given numbers are 390,838,479,203,181

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

The LCM of 390,838,479,203,181 is 2875999168770.

Find LCM of 390,838,479,203,181 with Prime Factorization

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

2 x 195 x 419 x 479 x 203 x 181 = 2875999168770

Therefore, the lowest common multiple of 390,838,479,203,181 is 2875999168770.

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.

390 x 838 x 479 x 203 x 181 = 5751998337540

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

838 : 1, 2, 419, 838

479 : 1, 479

203 : 1, 7, 29, 203

181 : 1, 181

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,838,479,203,181, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

838:2x 419

479:479

203:7x 29

181:181

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 = 5751998337540/(1x2)

LCM = 5751998337540/2

LCM = 2875999168770

Thus, we can understand that the LCM of 390,838,479,203,181 is 2875999168770.
