Given numbers are 561,540,781,295,210

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

The LCM of 561,540,781,295,210 is 2961036540.

Find LCM of 561,540,781,295,210 with Prime Factorization

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

2 x 3 x 5 x 11 x 17 x 18 x 71 x 59 x 7 = 2961036540

Therefore, the lowest common multiple of 561,540,781,295,210 is 2961036540.

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 540 x 781 x 295 x 210 = 14657130873000

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

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

781 : 1, 11, 71, 781

295 : 1, 5, 59, 295

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,540,781,295,210, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

540:2x 2x 3x 3x 3x 5

781:11x 71

295:5x 59

210:2x 3x 5x 7

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 5x 5x 11 = 4950

Therefore, the value for common factors is 4950.

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 = 14657130873000/(1x4950)

LCM = 14657130873000/4950

LCM = 2961036540

Thus, we can understand that the LCM of 561,540,781,295,210 is 2961036540.
