Calculate the LCM of 323,638,646,203

Given numbers are 323,638,646,203

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

The LCM of 323,638,646,203 is 1442518.

Find LCM of 323,638,646,203 with Prime Factorization


2 323, 638, 646, 203
17 323, 319, 323, 203
19 19, 319, 19, 203
29 1, 319, 1, 203
1, 11, 1, 7

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

2 x 17 x 19 x 29 x 1 x 11 x 1 x 7 = 1442518

Therefore, the lowest common multiple of 323,638,646,203 is 1442518.

LCM Formula to Find Lowest Common Multiple of 323,638,646,203

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.

323 x 638 x 646 x 203 = 27024132212

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.

323 : 1, 17, 19, 323

638 : 1, 2, 11, 22, 29, 58, 319, 638

646 : 1, 2, 17, 19, 34, 38, 323, 646

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,638,646,203, is 1.

Now, the common factors can be found like this.

323:17x 19

638:2x 11x 29

646:2x 17x 19

203:7x 29

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

2x 17x 19x 29 = 18734

Therefore, the value for common factors is 18734.

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 = 27024132212/(1x18734)

LCM = 27024132212/18734

LCM = 1442518

Thus, we can understand that the LCM of 323,638,646,203 is 1442518.
