Given numbers are 249,131,391,438

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

The LCM of 249,131,391,438 is 1862088234.

Find LCM of 249,131,391,438 with Prime Factorization

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

3 x 83 x 131 x 391 x 146 = 1862088234

Therefore, the lowest common multiple of 249,131,391,438 is 1862088234.

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 131 x 391 x 438 = 5586264702

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

131 : 1, 131

391 : 1, 17, 23, 391

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,131,391,438, is 1.

Now, the common factors can be found like this.

249:3x 83

131:131

391:17x 23

438:2x 3x 73

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

3 = 3

Therefore, the value for common factors is 3.

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 = 5586264702/(1x3)

LCM = 5586264702/3

LCM = 1862088234

Thus, we can understand that the LCM of 249,131,391,438 is 1862088234.
