Find LCM of 414,204,621,921 with Prime Factorization


2 414, 204, 621, 921
3 207, 102, 621, 921
3 69, 34, 207, 307
23 23, 34, 69, 307
1, 34, 3, 307

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

2 x 3 x 3 x 23 x 1 x 34 x 3 x 307 = 12963996

Therefore, the lowest common multiple of 414,204,621,921 is 12963996.

LCM Formula to Find Lowest Common Multiple of 414,204,621,921

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.

414 x 204 x 621 x 921 = 48303849096

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.

414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

621 : 1, 3, 9, 23, 27, 69, 207, 621

921 : 1, 3, 307, 921

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 414,204,621,921, is 3.

Now, the common factors can be found like this.

414:2x 3x 3x 23

204:2x 2x 3x 17

621:3x 3x 3x 23

921:3x 307

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

2x 3x 3x 3x 23 = 1242

Therefore, the value for common factors is 1242.

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 = 48303849096/(3x1242)

LCM = 48303849096/3726

LCM = 12963996

Thus, we can understand that the LCM of 414,204,621,921 is 12963996.
