Given numbers are 280,213,497,907,203

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

The LCM of 280,213,497,907,203 is 1568710920.

Find LCM of 280,213,497,907,203 with Prime Factorization

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

7 x 71 x 40 x 3 x 1 x 907 x 29 = 1568710920

Therefore, the lowest common multiple of 280,213,497,907,203 is 1568710920.

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.

280 x 213 x 497 x 907 x 203 = 5457545290680

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.

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

213 : 1, 3, 71, 213

497 : 1, 7, 71, 497

907 : 1, 907

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,213,497,907,203, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

213:3x 71

497:7x 71

907:907

203:7x 29

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

7x 7x 71 = 3479

Therefore, the value for common factors is 3479.

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 = 5457545290680/(1x3479)

LCM = 5457545290680/3479

LCM = 1568710920

Thus, we can understand that the LCM of 280,213,497,907,203 is 1568710920.
