Given numbers are 186,840,424,556,728

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

The LCM of 186,840,424,556,728 is 2493876840.

Find LCM of 186,840,424,556,728 with Prime Factorization

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

2 x 2 x 2 x 3 x 7 x 31 x 5 x 53 x 139 x 13 = 2493876840

Therefore, the lowest common multiple of 186,840,424,556,728 is 2493876840.

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.

186 x 840 x 424 x 556 x 728 = 26814163783680

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.

186 : 1, 2, 3, 6, 31, 62, 93, 186

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

424 : 1, 2, 4, 8, 53, 106, 212, 424

556 : 1, 2, 4, 139, 278, 556

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 186,840,424,556,728, is 2.

Now, the common factors can be found like this.

186:2x 3x 31

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

424:2x 2x 2x 53

556:2x 2x 139

728:2x 2x 2x 7x 13

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 2x 2x 2x 2x 3x 7 = 5376

Therefore, the value for common factors is 5376.

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 = 26814163783680/(2x5376)

LCM = 26814163783680/10752

LCM = 2493876840

Thus, we can understand that the LCM of 186,840,424,556,728 is 2493876840.
