Calculate the LCM of 647,678,726,924

Given numbers are 647,678,726,924

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

The LCM of 647,678,726,924 is 743100204.

Find LCM of 647,678,726,924 with Prime Factorization


2 647, 678, 726, 924
3 647, 339, 363, 462
11 647, 113, 121, 154
647, 113, 11, 14

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

2 x 3 x 11 x 647 x 113 x 11 x 14 = 743100204

Therefore, the lowest common multiple of 647,678,726,924 is 743100204.

LCM Formula to Find Lowest Common Multiple of 647,678,726,924

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.

647 x 678 x 726 x 924 = 294267680784

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.

647 : 1, 647

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

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,678,726,924, is 1.

Now, the common factors can be found like this.

647:647

678:2x 3x 113

726:2x 3x 11x 11

924:2x 2x 3x 7x 11

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 3x 3x 11 = 396

Therefore, the value for common factors is 396.

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 = 294267680784/(1x396)

LCM = 294267680784/396

LCM = 743100204

Thus, we can understand that the LCM of 647,678,726,924 is 743100204.
