Given numbers are 198,458,431,454

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

The LCM of 198,458,431,454 is 4436125254.

Find LCM of 198,458,431,454 with Prime Factorization

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

2 x 99 x 229 x 431 x 227 = 4436125254

Therefore, the lowest common multiple of 198,458,431,454 is 4436125254.

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.

198 x 458 x 431 x 454 = 17744501016

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

458 : 1, 2, 229, 458

431 : 1, 431

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,458,431,454, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

458:2x 229

431:431

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 17744501016/(1x4)

LCM = 17744501016/4

LCM = 4436125254

Thus, we can understand that the LCM of 198,458,431,454 is 4436125254.
