Given numbers are 461,456,678,406

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

The LCM of 461,456,678,406 is 4822144824.

Find LCM of 461,456,678,406 with Prime Factorization

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

2 x 3 x 461 x 76 x 113 x 203 = 4822144824

Therefore, the lowest common multiple of 461,456,678,406 is 4822144824.

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.

461 x 456 x 678 x 406 = 57865737888

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.

461 : 1, 461

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

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

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,456,678,406, is 1.

Now, the common factors can be found like this.

461:461

456:2x 2x 2x 3x 19

678:2x 3x 113

406:2x 7x 29

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 3 = 12

Therefore, the value for common factors is 12.

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 = 57865737888/(1x12)

LCM = 57865737888/12

LCM = 4822144824

Thus, we can understand that the LCM of 461,456,678,406 is 4822144824.
