Given numbers are 755,731,903,257

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

The LCM of 755,731,903,257 is 2978631285.

Find LCM of 755,731,903,257 with Prime Factorization

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

43 x 755 x 17 x 21 x 257 = 2978631285

Therefore, the lowest common multiple of 755,731,903,257 is 2978631285.

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.

755 x 731 x 903 x 257 = 128081145255

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.

755 : 1, 5, 151, 755

731 : 1, 17, 43, 731

903 : 1, 3, 7, 21, 43, 129, 301, 903

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,731,903,257, is 1.

Now, the common factors can be found like this.

755:5x 151

731:17x 43

903:3x 7x 43

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.

43 = 43

Therefore, the value for common factors is 43.

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 = 128081145255/(1x43)

LCM = 128081145255/43

LCM = 2978631285

Thus, we can understand that the LCM of 755,731,903,257 is 2978631285.
