Given numbers are 257,417,247,556

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

The LCM of 257,417,247,556 is 105882972.

Find LCM of 257,417,247,556 with Prime Factorization

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

139 x 257 x 3 x 247 x 4 = 105882972

Therefore, the lowest common multiple of 257,417,247,556 is 105882972.

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.

257 x 417 x 247 x 556 = 14717733108

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.

257 : 1, 257

417 : 1, 3, 139, 417

247 : 1, 13, 19, 247

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,417,247,556, is 1.

Now, the common factors can be found like this.

257:257

417:3x 139

247:13x 19

556:2x 2x 139

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

139 = 139

Therefore, the value for common factors is 139.

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 = 14717733108/(1x139)

LCM = 14717733108/139

LCM = 105882972

Thus, we can understand that the LCM of 257,417,247,556 is 105882972.
