Calculate the LCM of 561,687,660,546,259

Given numbers are 561,687,660,546,259

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

The LCM of 561,687,660,546,259 is 8651102460.

Find LCM of 561,687,660,546,259 with Prime Factorization


2 561, 687, 660, 546, 259
3 561, 687, 330, 273, 259
7 187, 229, 110, 91, 259
11 187, 229, 110, 13, 37
17, 229, 10, 13, 37

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

2 x 3 x 7 x 11 x 17 x 229 x 10 x 13 x 37 = 8651102460

Therefore, the lowest common multiple of 561,687,660,546,259 is 8651102460.

LCM Formula to Find Lowest Common Multiple of 561,687,660,546,259

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.

561 x 687 x 660 x 546 x 259 = 35971284028680

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

687 : 1, 3, 229, 687

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

259 : 1, 7, 37, 259

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,687,660,546,259, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

687:3x 229

660:2x 2x 3x 5x 11

546:2x 3x 7x 13

259:7x 37

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 7x 11 = 4158

Therefore, the value for common factors is 4158.

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 = 35971284028680/(1x4158)

LCM = 35971284028680/4158

LCM = 8651102460

Thus, we can understand that the LCM of 561,687,660,546,259 is 8651102460.
