Given numbers are 247,273,209,407

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

The LCM of 247,273,209,407 is 2111109.

Find LCM of 247,273,209,407 with Prime Factorization

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

11 x 13 x 19 x 1 x 21 x 1 x 37 = 2111109

Therefore, the lowest common multiple of 247,273,209,407 is 2111109.

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.

247 x 273 x 209 x 407 = 5735883153

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.

247 : 1, 13, 19, 247

273 : 1, 3, 7, 13, 21, 39, 91, 273

209 : 1, 11, 19, 209

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,273,209,407, is 1.

Now, the common factors can be found like this.

247:13x 19

273:3x 7x 13

209:11x 19

407:11x 37

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

11x 13x 19 = 2717

Therefore, the value for common factors is 2717.

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 = 5735883153/(1x2717)

LCM = 5735883153/2717

LCM = 2111109

Thus, we can understand that the LCM of 247,273,209,407 is 2111109.
