Given numbers are 870,489,193,774,181

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

The LCM of 870,489,193,774,181 is 639046486170.

Find LCM of 870,489,193,774,181 with Prime Factorization

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

2 x 3 x 145 x 163 x 193 x 129 x 181 = 639046486170

Therefore, the lowest common multiple of 870,489,193,774,181 is 639046486170.

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.

870 x 489 x 193 x 774 x 181 = 11502836751060

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.

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

489 : 1, 3, 163, 489

193 : 1, 193

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

181 : 1, 181

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,489,193,774,181, is 1.

Now, the common factors can be found like this.

870:2x 3x 5x 29

489:3x 163

193:193

774:2x 3x 3x 43

181:181

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 11502836751060/(1x18)

LCM = 11502836751060/18

LCM = 639046486170

Thus, we can understand that the LCM of 870,489,193,774,181 is 639046486170.
