Calculate the LCM of 137,759,420,105

Given numbers are 137,759,420,105

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

The LCM of 137,759,420,105 is 14557620.

Find LCM of 137,759,420,105 with Prime Factorization


3 137, 759, 420, 105
5 137, 253, 140, 35
7 137, 253, 28, 7
137, 253, 4, 1

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

3 x 5 x 7 x 137 x 253 x 4 x 1 = 14557620

Therefore, the lowest common multiple of 137,759,420,105 is 14557620.

LCM Formula to Find Lowest Common Multiple of 137,759,420,105

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 759 x 420 x 105 = 4585650300

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

759 : 1, 3, 11, 23, 33, 69, 253, 759

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

105 : 1, 3, 5, 7, 15, 21, 35, 105

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,759,420,105, is 1.

Now, the common factors can be found like this.

137:137

759:3x 11x 23

420:2x 2x 3x 5x 7

105:3x 5x 7

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

3x 3x 5x 7 = 315

Therefore, the value for common factors is 315.

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 = 4585650300/(1x315)

LCM = 4585650300/315

LCM = 14557620

Thus, we can understand that the LCM of 137,759,420,105 is 14557620.
