Given numbers are 261,197,774,515,864

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

The LCM of 261,197,774,515,864 is 109308428640.

Find LCM of 261,197,774,515,864 with Prime Factorization

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

2 x 3 x 3 x 29 x 197 x 43 x 515 x 48 = 109308428640

Therefore, the lowest common multiple of 261,197,774,515,864 is 109308428640.

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 197 x 774 x 515 x 864 = 17707965439680

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

197 : 1, 197

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

515 : 1, 5, 103, 515

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,197,774,515,864, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

197:197

774:2x 3x 3x 43

515:5x 103

864:2x 2x 2x 2x 2x 3x 3x 3

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 3x 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 17707965439680/(1x162)

LCM = 17707965439680/162

LCM = 109308428640

Thus, we can understand that the LCM of 261,197,774,515,864 is 109308428640.
