Given numbers are 394,638,290,419

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

The LCM of 394,638,290,419 is 263312170.

Find LCM of 394,638,290,419 with Prime Factorization

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

2 x 29 x 197 x 11 x 5 x 419 = 263312170

Therefore, the lowest common multiple of 394,638,290,419 is 263312170.

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.

394 x 638 x 290 x 419 = 30544211720

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.

394 : 1, 2, 197, 394

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

290 : 1, 2, 5, 10, 29, 58, 145, 290

419 : 1, 419

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,638,290,419, is 1.

Now, the common factors can be found like this.

394:2x 197

638:2x 11x 29

290:2x 5x 29

419:419

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 29 = 116

Therefore, the value for common factors is 116.

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 = 30544211720/(1x116)

LCM = 30544211720/116

LCM = 263312170

Thus, we can understand that the LCM of 394,638,290,419 is 263312170.
