Given numbers are 247,127,209,228

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

The LCM of 247,127,209,228 is 4140708.

Find LCM of 247,127,209,228 with Prime Factorization

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

19 x 13 x 127 x 11 x 12 = 4140708

Therefore, the lowest common multiple of 247,127,209,228 is 4140708.

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 127 x 209 x 228 = 1494795588

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

127 : 1, 127

209 : 1, 11, 19, 209

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,127,209,228, is 1.

Now, the common factors can be found like this.

247:13x 19

127:127

209:11x 19

228:2x 2x 3x 19

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

19x 19 = 361

Therefore, the value for common factors is 361.

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 = 1494795588/(1x361)

LCM = 1494795588/361

LCM = 4140708

Thus, we can understand that the LCM of 247,127,209,228 is 4140708.
