Given numbers are 788,306,840,257,825

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

The LCM of 788,306,840,257,825 is 119292049800.

Find LCM of 788,306,840,257,825 with Prime Factorization

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

2 x 2 x 3 x 5 x 197 x 51 x 14 x 257 x 55 = 119292049800

Therefore, the lowest common multiple of 788,306,840,257,825 is 119292049800.

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.

788 x 306 x 840 x 257 x 825 = 42945137928000

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.

788 : 1, 2, 4, 197, 394, 788

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

257 : 1, 257

825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,306,840,257,825, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

306:2x 3x 3x 17

840:2x 2x 2x 3x 5x 7

257:257

825:3x 5x 5x 11

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 3x 3x 5 = 360

Therefore, the value for common factors is 360.

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 = 42945137928000/(1x360)

LCM = 42945137928000/360

LCM = 119292049800

Thus, we can understand that the LCM of 788,306,840,257,825 is 119292049800.
