Given numbers are 454,198,340,673

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

The LCM of 454,198,340,673 is 5142271860.

Find LCM of 454,198,340,673 with Prime Factorization

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

2 x 227 x 99 x 170 x 673 = 5142271860

Therefore, the lowest common multiple of 454,198,340,673 is 5142271860.

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.

454 x 198 x 340 x 673 = 20569087440

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.

454 : 1, 2, 227, 454

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

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

673 : 1, 673

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,198,340,673, is 1.

Now, the common factors can be found like this.

454:2x 227

198:2x 3x 3x 11

340:2x 2x 5x 17

673:673

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 = 20569087440/(1x4)

LCM = 20569087440/4

LCM = 5142271860

Thus, we can understand that the LCM of 454,198,340,673 is 5142271860.
