Calculate the LCM of 489,154,261,858

Given numbers are 489,154,261,858

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

The LCM of 489,154,261,858 is 85171086.

Find LCM of 489,154,261,858 with Prime Factorization


2 489, 154, 261, 858
3 489, 77, 261, 429
11 163, 77, 87, 143
163, 7, 87, 13

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

2 x 3 x 11 x 163 x 7 x 87 x 13 = 85171086

Therefore, the lowest common multiple of 489,154,261,858 is 85171086.

LCM Formula to Find Lowest Common Multiple of 489,154,261,858

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.

489 x 154 x 261 x 858 = 16863875028

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.

489 : 1, 3, 163, 489

154 : 1, 2, 7, 11, 14, 22, 77, 154

261 : 1, 3, 9, 29, 87, 261

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,154,261,858, is 1.

Now, the common factors can be found like this.

489:3x 163

154:2x 7x 11

261:3x 3x 29

858:2x 3x 11x 13

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 11 = 198

Therefore, the value for common factors is 198.

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 = 16863875028/(1x198)

LCM = 16863875028/198

LCM = 85171086

Thus, we can understand that the LCM of 489,154,261,858 is 85171086.
