The LCM of 678,663,169,338 is 1947894.

Find LCM of 678,663,169,338 with Prime Factorization


2 678, 663, 169, 338
3 339, 663, 169, 169
13 113, 221, 169, 169
13 113, 17, 13, 13
113, 17, 1, 1

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

2 x 3 x 13 x 13 x 113 x 17 x 1 x 1 = 1947894

Therefore, the lowest common multiple of 678,663,169,338 is 1947894.

LCM Formula to Find Lowest Common Multiple of 678,663,169,338

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.

678 x 663 x 169 x 338 = 25677138708

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

663 : 1, 3, 13, 17, 39, 51, 221, 663

169 : 1, 13, 169

338 : 1, 2, 13, 26, 169, 338

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,663,169,338, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

663:3x 13x 17

169:13x 13

338:2x 13x 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 13x 13x 13 = 13182

Therefore, the value for common factors is 13182.

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 = 25677138708/(1x13182)

LCM = 25677138708/13182

LCM = 1947894

Thus, we can understand that the LCM of 678,663,169,338 is 1947894.
