Given numbers are 247,771,171,705

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

The LCM of 247,771,171,705 is 134258085.

Find LCM of 247,771,171,705 with Prime Factorization

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

3 x 19 x 13 x 257 x 3 x 235 = 134258085

Therefore, the lowest common multiple of 247,771,171,705 is 134258085.

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.

247 x 771 x 171 x 705 = 22958132535

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.

247 : 1, 13, 19, 247

771 : 1, 3, 257, 771

171 : 1, 3, 9, 19, 57, 171

705 : 1, 3, 5, 15, 47, 141, 235, 705

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,771,171,705, is 1.

Now, the common factors can be found like this.

247:13x 19

771:3x 257

171:3x 3x 19

705:3x 5x 47

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

3x 3x 19 = 171

Therefore, the value for common factors is 171.

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 = 22958132535/(1x171)

LCM = 22958132535/171

LCM = 134258085

Thus, we can understand that the LCM of 247,771,171,705 is 134258085.
