Calculate the LCM of 810,689,735,137

Given numbers are 810,689,735,137

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

The LCM of 810,689,735,137 is 3746458170.

Find LCM of 810,689,735,137 with Prime Factorization


3 810, 689, 735, 137
5 270, 689, 245, 137
54, 689, 49, 137

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

3 x 5 x 54 x 689 x 49 x 137 = 3746458170

Therefore, the lowest common multiple of 810,689,735,137 is 3746458170.

LCM Formula to Find Lowest Common Multiple of 810,689,735,137

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.

810 x 689 x 735 x 137 = 56196872550

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

689 : 1, 13, 53, 689

735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735

137 : 1, 137

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,689,735,137, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

689:13x 53

735:3x 5x 7x 7

137:137

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 56196872550/(1x15)

LCM = 56196872550/15

LCM = 3746458170

Thus, we can understand that the LCM of 810,689,735,137 is 3746458170.
