Given numbers are 203,242,454,820

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

The LCM of 203,242,454,820 is 4572156820.

Find LCM of 203,242,454,820 with Prime Factorization

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

2 x 203 x 121 x 227 x 410 = 4572156820

Therefore, the lowest common multiple of 203,242,454,820 is 4572156820.

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.

203 x 242 x 454 x 820 = 18288627280

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.

203 : 1, 7, 29, 203

242 : 1, 2, 11, 22, 121, 242

454 : 1, 2, 227, 454

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,242,454,820, is 1.

Now, the common factors can be found like this.

203:7x 29

242:2x 11x 11

454:2x 227

820:2x 2x 5x 41

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 = 18288627280/(1x4)

LCM = 18288627280/4

LCM = 4572156820

Thus, we can understand that the LCM of 203,242,454,820 is 4572156820.
