Given numbers are 518,976,689,647

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

The LCM of 518,976,689,647 is 112686809872.

Find LCM of 518,976,689,647 with Prime Factorization

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

2 x 259 x 488 x 689 x 647 = 112686809872

Therefore, the lowest common multiple of 518,976,689,647 is 112686809872.

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.

518 x 976 x 689 x 647 = 225373619744

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.

518 : 1, 2, 7, 14, 37, 74, 259, 518

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

689 : 1, 13, 53, 689

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,976,689,647, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

976:2x 2x 2x 2x 61

689:13x 53

647:647

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

2 = 2

Therefore, the value for common factors is 2.

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 = 225373619744/(1x2)

LCM = 225373619744/2

LCM = 112686809872

Thus, we can understand that the LCM of 518,976,689,647 is 112686809872.
