Given numbers are 605,749,365,405

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

The LCM of 605,749,365,405 is 2679446385.

Find LCM of 605,749,365,405 with Prime Factorization

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

5 x 121 x 749 x 73 x 81 = 2679446385

Therefore, the lowest common multiple of 605,749,365,405 is 2679446385.

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 749 x 365 x 405 = 66986159625

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

749 : 1, 7, 107, 749

365 : 1, 5, 73, 365

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,749,365,405, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

749:7x 107

365:5x 73

405:3x 3x 3x 3x 5

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 66986159625/(1x25)

LCM = 66986159625/25

LCM = 2679446385

Thus, we can understand that the LCM of 605,749,365,405 is 2679446385.
