Calculate the LCM of 447,731,247,298

Given numbers are 447,731,247,298

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

The LCM of 447,731,247,298 is 161417958.

Find LCM of 447,731,247,298 with Prime Factorization


149 447, 731, 247, 298
3, 731, 247, 2

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

149 x 3 x 731 x 247 x 2 = 161417958

Therefore, the lowest common multiple of 447,731,247,298 is 161417958.

LCM Formula to Find Lowest Common Multiple of 447,731,247,298

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.

447 x 731 x 247 x 298 = 24051275742

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.

447 : 1, 3, 149, 447

731 : 1, 17, 43, 731

247 : 1, 13, 19, 247

298 : 1, 2, 149, 298

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,731,247,298, is 1.

Now, the common factors can be found like this.

447:3x 149

731:17x 43

247:13x 19

298:2x 149

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 = 24051275742/(1x149)

LCM = 24051275742/149

LCM = 161417958

Thus, we can understand that the LCM of 447,731,247,298 is 161417958.
