Given numbers are 678,261,236,663

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

The LCM of 678,261,236,663 is 1538236908.

Find LCM of 678,261,236,663 with Prime Factorization

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

2 x 3 x 113 x 87 x 118 x 221 = 1538236908

Therefore, the lowest common multiple of 678,261,236,663 is 1538236908.

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.

678 x 261 x 236 x 663 = 27688264344

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

261 : 1, 3, 9, 29, 87, 261

236 : 1, 2, 4, 59, 118, 236

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,261,236,663, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

261:3x 3x 29

236:2x 2x 59

663:3x 13x 17

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 27688264344/(1x18)

LCM = 27688264344/18

LCM = 1538236908

Thus, we can understand that the LCM of 678,261,236,663 is 1538236908.
