Given numbers are 249,561,306,257

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

The LCM of 249,561,306,257 is 71800146.

Find LCM of 249,561,306,257 with Prime Factorization

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

3 x 17 x 83 x 11 x 6 x 257 = 71800146

Therefore, the lowest common multiple of 249,561,306,257 is 71800146.

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.

249 x 561 x 306 x 257 = 10985422338

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.

249 : 1, 3, 83, 249

561 : 1, 3, 11, 17, 33, 51, 187, 561

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,561,306,257, is 1.

Now, the common factors can be found like this.

249:3x 83

561:3x 11x 17

306:2x 3x 3x 17

257:257

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

3x 3x 17 = 153

Therefore, the value for common factors is 153.

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 = 10985422338/(1x153)

LCM = 10985422338/153

LCM = 71800146

Thus, we can understand that the LCM of 249,561,306,257 is 71800146.

Here are some samples of LCM of two or more Numbers calculations.
