Given numbers are 678,856,455

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

The LCM of 678,856,455 is 132033720.

Find LCM of 678,856,455 with Prime Factorization

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

2 x 339 x 428 x 455 = 132033720

Therefore, the lowest common multiple of 678,856,455 is 132033720.

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 856 x 455 = 264067440

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,856,455, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

856:2x 2x 2x 107

455:5x 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.

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 = 264067440/(1x2)

LCM = 264067440/2

LCM = 132033720

Thus, we can understand that the LCM of 678,856,455 is 132033720.

Here are some samples of LCM of two or more Numbers calculations.
