Given numbers are 386,720,386,478

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

The LCM of 386,720,386,478 is 33211440.

Find LCM of 386,720,386,478 with Prime Factorization

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

2 x 193 x 1 x 360 x 1 x 239 = 33211440

Therefore, the lowest common multiple of 386,720,386,478 is 33211440.

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 720 x 386 x 478 = 51278463360

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

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

386 : 1, 2, 193, 386

478 : 1, 2, 239, 478

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,720,386,478, is 2.

Now, the common factors can be found like this.

386:2x 193

720:2x 2x 2x 2x 3x 3x 5

386:2x 193

478:2x 239

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 193 = 772

Therefore, the value for common factors is 772.

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 = 51278463360/(2x772)

LCM = 51278463360/1544

LCM = 33211440

Thus, we can understand that the LCM of 386,720,386,478 is 33211440.
