Given numbers are 547,228,209,391

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

The LCM of 547,228,209,391 is 536403516.

Find LCM of 547,228,209,391 with Prime Factorization

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

19 x 547 x 12 x 11 x 391 = 536403516

Therefore, the lowest common multiple of 547,228,209,391 is 536403516.

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.

547 x 228 x 209 x 391 = 10191666804

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.

547 : 1, 547

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

209 : 1, 11, 19, 209

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,228,209,391, is 1.

Now, the common factors can be found like this.

547:547

228:2x 2x 3x 19

209:11x 19

391:17x 23

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

19 = 19

Therefore, the value for common factors is 19.

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 = 10191666804/(1x19)

LCM = 10191666804/19

LCM = 536403516

Thus, we can understand that the LCM of 547,228,209,391 is 536403516.
