Given numbers are 605,311,622,417

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

The LCM of 605,311,622,417 is 156921270.

Find LCM of 605,311,622,417 with Prime Factorization

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

311 x 605 x 1 x 2 x 417 = 156921270

Therefore, the lowest common multiple of 605,311,622,417 is 156921270.

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.

605 x 311 x 622 x 417 = 48802514970

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.

605 : 1, 5, 11, 55, 121, 605

311 : 1, 311

622 : 1, 2, 311, 622

417 : 1, 3, 139, 417

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,311,622,417, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

311:311

622:2x 311

417:3x 139

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

311 = 311

Therefore, the value for common factors is 311.

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 = 48802514970/(1x311)

LCM = 48802514970/311

LCM = 156921270

Thus, we can understand that the LCM of 605,311,622,417 is 156921270.
