Given numbers are 128,615,782,738,293

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

The LCM of 128,615,782,738,293 is 27055198080.

Find LCM of 128,615,782,738,293 with Prime Factorization

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

2 x 3 x 41 x 64 x 5 x 391 x 3 x 293 = 27055198080

Therefore, the lowest common multiple of 128,615,782,738,293 is 27055198080.

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.

128 x 615 x 782 x 738 x 293 = 13311157455360

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

615 : 1, 3, 5, 15, 41, 123, 205, 615

782 : 1, 2, 17, 23, 34, 46, 391, 782

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

293 : 1, 293

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,615,782,738,293, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

615:3x 5x 41

782:2x 17x 23

738:2x 3x 3x 41

293:293

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 3x 41 = 492

Therefore, the value for common factors is 492.

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 = 13311157455360/(1x492)

LCM = 13311157455360/492

LCM = 27055198080

Thus, we can understand that the LCM of 128,615,782,738,293 is 27055198080.
