Find LCM of 687,884,918,828 with Prime Factorization


2 687, 884, 918, 828
2 687, 442, 459, 414
3 687, 221, 459, 207
3 229, 221, 153, 69
17 229, 221, 51, 23
229, 13, 3, 23

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

2 x 2 x 3 x 3 x 17 x 229 x 13 x 3 x 23 = 125712756

Therefore, the lowest common multiple of 687,884,918,828 is 125712756.

LCM Formula to Find Lowest Common Multiple of 687,884,918,828

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.

687 x 884 x 918 x 828 = 461617240032

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.

687 : 1, 3, 229, 687

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,884,918,828, is 1.

Now, the common factors can be found like this.

687:3x 229

884:2x 2x 13x 17

918:2x 3x 3x 3x 17

828:2x 2x 3x 3x 23

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 2x 3x 3x 3x 17 = 3672

Therefore, the value for common factors is 3672.

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 = 461617240032/(1x3672)

LCM = 461617240032/3672

LCM = 125712756

Thus, we can understand that the LCM of 687,884,918,828 is 125712756.
