Calculate the LCM of 679,747,350,405

Given numbers are 679,747,350,405

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

The LCM of 679,747,350,405 is 228245850.

Find LCM of 679,747,350,405 with Prime Factorization


3 679, 747, 350, 405
3 679, 249, 350, 135
5 679, 83, 350, 45
7 679, 83, 70, 9
97, 83, 10, 9

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

3 x 3 x 5 x 7 x 97 x 83 x 10 x 9 = 228245850

Therefore, the lowest common multiple of 679,747,350,405 is 228245850.

LCM Formula to Find Lowest Common Multiple of 679,747,350,405

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.

679 x 747 x 350 x 405 = 71897442750

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.

679 : 1, 7, 97, 679

747 : 1, 3, 9, 83, 249, 747

350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,747,350,405, is 1.

Now, the common factors can be found like this.

679:7x 97

747:3x 3x 83

350:2x 5x 5x 7

405:3x 3x 3x 3x 5

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 = 71897442750/(1x315)

LCM = 71897442750/315

LCM = 228245850

Thus, we can understand that the LCM of 679,747,350,405 is 228245850.
