Given numbers are 457,545,533,407,221

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

The LCM of 457,545,533,407,221 is 918508631755.

Find LCM of 457,545,533,407,221 with Prime Factorization

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

13 x 457 x 545 x 41 x 407 x 17 = 918508631755

Therefore, the lowest common multiple of 457,545,533,407,221 is 918508631755.

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.

457 x 545 x 533 x 407 x 221 = 11940612212815

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.

457 : 1, 457

545 : 1, 5, 109, 545

533 : 1, 13, 41, 533

407 : 1, 11, 37, 407

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,545,533,407,221, is 1.

Now, the common factors can be found like this.

457:457

545:5x 109

533:13x 41

407:11x 37

221:13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 11940612212815/(1x13)

LCM = 11940612212815/13

LCM = 918508631755

Thus, we can understand that the LCM of 457,545,533,407,221 is 918508631755.
