Given numbers are 298,211,447,781

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

The LCM of 298,211,447,781 is 147323154.

Find LCM of 298,211,447,781 with Prime Factorization

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

149 x 2 x 211 x 3 x 781 = 147323154

Therefore, the lowest common multiple of 298,211,447,781 is 147323154.

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.

298 x 211 x 447 x 781 = 21951149946

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.

298 : 1, 2, 149, 298

211 : 1, 211

447 : 1, 3, 149, 447

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,211,447,781, is 1.

Now, the common factors can be found like this.

298:2x 149

211:211

447:3x 149

781:11x 71

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

149 = 149

Therefore, the value for common factors is 149.

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 = 21951149946/(1x149)

LCM = 21951149946/149

LCM = 147323154

Thus, we can understand that the LCM of 298,211,447,781 is 147323154.
