The LCM of 676,154,646,551 is 487571084.

Find LCM of 676,154,646,551 with Prime Factorization


2 676, 154, 646, 551
19 338, 77, 323, 551
338, 77, 17, 29

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

2 x 19 x 338 x 77 x 17 x 29 = 487571084

Therefore, the lowest common multiple of 676,154,646,551 is 487571084.

LCM Formula to Find Lowest Common Multiple of 676,154,646,551

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.

676 x 154 x 646 x 551 = 37055402384

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.

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

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

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

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,154,646,551, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

154:2x 7x 11

646:2x 17x 19

551:19x 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 2x 19 = 76

Therefore, the value for common factors is 76.

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 = 37055402384/(1x76)

LCM = 37055402384/76

LCM = 487571084

Thus, we can understand that the LCM of 676,154,646,551 is 487571084.
