Given numbers are 728,260,916,346,836

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

The LCM of 728,260,916,346,836 is 30139028920.

Find LCM of 728,260,916,346,836 with Prime Factorization

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

2 x 2 x 13 x 14 x 5 x 229 x 173 x 209 = 30139028920

Therefore, the lowest common multiple of 728,260,916,346,836 is 30139028920.

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.

728 x 260 x 916 x 346 x 836 = 50151344122880

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.

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

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

916 : 1, 2, 4, 229, 458, 916

346 : 1, 2, 173, 346

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,260,916,346,836, is 2.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

260:2x 2x 5x 13

916:2x 2x 229

346:2x 173

836:2x 2x 11x 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 2x 2x 13 = 832

Therefore, the value for common factors is 832.

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 = 50151344122880/(2x832)

LCM = 50151344122880/1664

LCM = 30139028920

Thus, we can understand that the LCM of 728,260,916,346,836 is 30139028920.
