Given numbers are 131,124,665,394,257

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

The LCM of 131,124,665,394,257 is 546907621540.

Find LCM of 131,124,665,394,257 with Prime Factorization

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

2 x 131 x 62 x 665 x 197 x 257 = 546907621540

Therefore, the lowest common multiple of 131,124,665,394,257 is 546907621540.

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.

131 x 124 x 665 x 394 x 257 = 1093815243080

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.

131 : 1, 131

124 : 1, 2, 4, 31, 62, 124

665 : 1, 5, 7, 19, 35, 95, 133, 665

394 : 1, 2, 197, 394

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,124,665,394,257, is 1.

Now, the common factors can be found like this.

131:131

124:2x 2x 31

665:5x 7x 19

394:2x 197

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 1093815243080/(1x2)

LCM = 1093815243080/2

LCM = 546907621540

Thus, we can understand that the LCM of 131,124,665,394,257 is 546907621540.
