Given numbers are 261,921,676,705

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

The LCM of 261,921,676,705 is 12728975220.

Find LCM of 261,921,676,705 with Prime Factorization

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

3 x 87 x 307 x 676 x 235 = 12728975220

Therefore, the lowest common multiple of 261,921,676,705 is 12728975220.

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.

261 x 921 x 676 x 705 = 114560776980

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.

261 : 1, 3, 9, 29, 87, 261

921 : 1, 3, 307, 921

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

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 261,921,676,705, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

921:3x 307

676:2x 2x 13x 13

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 3 = 9

Therefore, the value for common factors is 9.

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 = 114560776980/(1x9)

LCM = 114560776980/9

LCM = 12728975220

Thus, we can understand that the LCM of 261,921,676,705 is 12728975220.
