Given numbers are 218,247,454,455

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

The LCM of 218,247,454,455 is 427806470.

Find LCM of 218,247,454,455 with Prime Factorization

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

2 x 13 x 109 x 19 x 227 x 35 = 427806470

Therefore, the lowest common multiple of 218,247,454,455 is 427806470.

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.

218 x 247 x 454 x 455 = 11122968220

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.

218 : 1, 2, 109, 218

247 : 1, 13, 19, 247

454 : 1, 2, 227, 454

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,247,454,455, is 1.

Now, the common factors can be found like this.

218:2x 109

247:13x 19

454:2x 227

455:5x 7x 13

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 11122968220/(1x26)

LCM = 11122968220/26

LCM = 427806470

Thus, we can understand that the LCM of 218,247,454,455 is 427806470.
