Given numbers are 398,186,720,813

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

The LCM of 398,186,720,813 is 1203695280.

Find LCM of 398,186,720,813 with Prime Factorization

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

2 x 3 x 199 x 31 x 120 x 271 = 1203695280

Therefore, the lowest common multiple of 398,186,720,813 is 1203695280.

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.

398 x 186 x 720 x 813 = 43333030080

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.

398 : 1, 2, 199, 398

186 : 1, 2, 3, 6, 31, 62, 93, 186

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

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,186,720,813, is 1.

Now, the common factors can be found like this.

398:2x 199

186:2x 3x 31

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

813:3x 271

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 43333030080/(1x36)

LCM = 43333030080/36

LCM = 1203695280

Thus, we can understand that the LCM of 398,186,720,813 is 1203695280.
