Given numbers are 386,424,393,398

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

The LCM of 386,424,393,398 is 6399835224.

Find LCM of 386,424,393,398 with Prime Factorization

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

2 x 193 x 212 x 393 x 199 = 6399835224

Therefore, the lowest common multiple of 386,424,393,398 is 6399835224.

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.

386 x 424 x 393 x 398 = 25599340896

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.

386 : 1, 2, 193, 386

424 : 1, 2, 4, 8, 53, 106, 212, 424

393 : 1, 3, 131, 393

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,424,393,398, is 1.

Now, the common factors can be found like this.

386:2x 193

424:2x 2x 2x 53

393:3x 131

398:2x 199

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 25599340896/(1x4)

LCM = 25599340896/4

LCM = 6399835224

Thus, we can understand that the LCM of 386,424,393,398 is 6399835224.
