Given numbers are 909,213,993,187,280

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

The LCM of 909,213,993,187,280 is 1118535735240.

Find LCM of 909,213,993,187,280 with Prime Factorization

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

3 x 303 x 71 x 331 x 187 x 280 = 1118535735240

Therefore, the lowest common multiple of 909,213,993,187,280 is 1118535735240.

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.

909 x 213 x 993 x 187 x 280 = 10066821617160

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.

909 : 1, 3, 9, 101, 303, 909

213 : 1, 3, 71, 213

993 : 1, 3, 331, 993

187 : 1, 11, 17, 187

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,213,993,187,280, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

213:3x 71

993:3x 331

187:11x 17

280:2x 2x 2x 5x 7

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 10066821617160/(1x9)

LCM = 10066821617160/9

LCM = 1118535735240

Thus, we can understand that the LCM of 909,213,993,187,280 is 1118535735240.
