Given numbers are 781,540,920,887,380

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

The LCM of 781,540,920,887,380 is 326948874120.

Find LCM of 781,540,920,887,380 with Prime Factorization

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

2 x 2 x 5 x 781 x 27 x 46 x 887 x 19 = 326948874120

Therefore, the lowest common multiple of 781,540,920,887,380 is 326948874120.

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.

781 x 540 x 920 x 887 x 380 = 130779549648000

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.

781 : 1, 11, 71, 781

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

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

887 : 1, 887

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,540,920,887,380, is 1.

Now, the common factors can be found like this.

781:11x 71

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

920:2x 2x 2x 5x 23

887:887

380:2x 2x 5x 19

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

2x 2x 2x 2x 5x 5 = 400

Therefore, the value for common factors is 400.

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 = 130779549648000/(1x400)

LCM = 130779549648000/400

LCM = 326948874120

Thus, we can understand that the LCM of 781,540,920,887,380 is 326948874120.
