Calculate the LCM of 137,904,815,489

Given numbers are 137,904,815,489

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

The LCM of 137,904,815,489 is 302808360.

Find LCM of 137,904,815,489 with Prime Factorization


163 137, 904, 815, 489
137, 904, 5, 3

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

163 x 137 x 904 x 5 x 3 = 302808360

Therefore, the lowest common multiple of 137,904,815,489 is 302808360.

LCM Formula to Find Lowest Common Multiple of 137,904,815,489

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.

137 x 904 x 815 x 489 = 49357762680

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.

137 : 1, 137

904 : 1, 2, 4, 8, 113, 226, 452, 904

815 : 1, 5, 163, 815

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,904,815,489, is 1.

Now, the common factors can be found like this.

137:137

904:2x 2x 2x 113

815:5x 163

489:3x 163

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

163 = 163

Therefore, the value for common factors is 163.

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 = 49357762680/(1x163)

LCM = 49357762680/163

LCM = 302808360

Thus, we can understand that the LCM of 137,904,815,489 is 302808360.
