The LCM of 853,204,844,221 is 477314916.

Find LCM of 853,204,844,221 with Prime Factorization


2 853, 204, 844, 221
2 853, 102, 422, 221
17 853, 51, 211, 221
853, 3, 211, 13

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

2 x 2 x 17 x 853 x 3 x 211 x 13 = 477314916

Therefore, the lowest common multiple of 853,204,844,221 is 477314916.

LCM Formula to Find Lowest Common Multiple of 853,204,844,221

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.

853 x 204 x 844 x 221 = 32457414288

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.

853 : 1, 853

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

844 : 1, 2, 4, 211, 422, 844

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,204,844,221, is 1.

Now, the common factors can be found like this.

853:853

204:2x 2x 3x 17

844:2x 2x 211

221:13x 17

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

2x 2x 17 = 68

Therefore, the value for common factors is 68.

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 = 32457414288/(1x68)

LCM = 32457414288/68

LCM = 477314916

Thus, we can understand that the LCM of 853,204,844,221 is 477314916.
