Given numbers are 605,276,221,454

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

The LCM of 605,276,221,454 is 8376885660.

Find LCM of 605,276,221,454 with Prime Factorization

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

2 x 605 x 138 x 221 x 227 = 8376885660

Therefore, the lowest common multiple of 605,276,221,454 is 8376885660.

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 276 x 221 x 454 = 16753771320

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

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

221 : 1, 13, 17, 221

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,276,221,454, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

276:2x 2x 3x 23

221:13x 17

454:2x 227

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 = 16753771320/(1x2)

LCM = 16753771320/2

LCM = 8376885660

Thus, we can understand that the LCM of 605,276,221,454 is 8376885660.
