Given numbers are 858,259,239,221

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

The LCM of 858,259,239,221 is 902887986.

Find LCM of 858,259,239,221 with Prime Factorization

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

13 x 66 x 259 x 239 x 17 = 902887986

Therefore, the lowest common multiple of 858,259,239,221 is 902887986.

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.

858 x 259 x 239 x 221 = 11737543818

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.

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

259 : 1, 7, 37, 259

239 : 1, 239

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,259,239,221, is 1.

Now, the common factors can be found like this.

858:2x 3x 11x 13

259:7x 37

239:239

221:13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 11737543818/(1x13)

LCM = 11737543818/13

LCM = 902887986

Thus, we can understand that the LCM of 858,259,239,221 is 902887986.
