Calculate the LCM of 731,289,258,141

Given numbers are 731,289,258,141

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

The LCM of 731,289,258,141 is 3504414.

Find LCM of 731,289,258,141 with Prime Factorization


3 731, 289, 258, 141
17 731, 289, 86, 47
43 43, 17, 86, 47
1, 17, 2, 47

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

3 x 17 x 43 x 1 x 17 x 2 x 47 = 3504414

Therefore, the lowest common multiple of 731,289,258,141 is 3504414.

LCM Formula to Find Lowest Common Multiple of 731,289,258,141

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.

731 x 289 x 258 x 141 = 7685179902

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.

731 : 1, 17, 43, 731

289 : 1, 17, 289

258 : 1, 2, 3, 6, 43, 86, 129, 258

141 : 1, 3, 47, 141

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,289,258,141, is 1.

Now, the common factors can be found like this.

731:17x 43

289:17x 17

258:2x 3x 43

141:3x 47

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

3x 17x 43 = 2193

Therefore, the value for common factors is 2193.

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 = 7685179902/(1x2193)

LCM = 7685179902/2193

LCM = 3504414

Thus, we can understand that the LCM of 731,289,258,141 is 3504414.
