Calculate the LCM of 546,865,405,788

Given numbers are 546,865,405,788

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

The LCM of 546,865,405,788 is 5024221020.

Find LCM of 546,865,405,788 with Prime Factorization


2 546, 865, 405, 788
3 273, 865, 405, 394
5 91, 865, 135, 394
91, 173, 27, 394

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

2 x 3 x 5 x 91 x 173 x 27 x 394 = 5024221020

Therefore, the lowest common multiple of 546,865,405,788 is 5024221020.

LCM Formula to Find Lowest Common Multiple of 546,865,405,788

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.

546 x 865 x 405 x 788 = 150726630600

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.

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

865 : 1, 5, 173, 865

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

788 : 1, 2, 4, 197, 394, 788

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,865,405,788, is 1.

Now, the common factors can be found like this.

546:2x 3x 7x 13

865:5x 173

405:3x 3x 3x 3x 5

788:2x 2x 197

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 5 = 30

Therefore, the value for common factors is 30.

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 = 150726630600/(1x30)

LCM = 150726630600/30

LCM = 5024221020

Thus, we can understand that the LCM of 546,865,405,788 is 5024221020.
