Calculate the LCM of 685,881,881,645

Given numbers are 685,881,881,645

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

The LCM of 685,881,881,645 is 77849565.

Find LCM of 685,881,881,645 with Prime Factorization


5 685, 881, 881, 645
881 137, 881, 881, 129
137, 1, 1, 129

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

5 x 881 x 137 x 1 x 1 x 129 = 77849565

Therefore, the lowest common multiple of 685,881,881,645 is 77849565.

LCM Formula to Find Lowest Common Multiple of 685,881,881,645

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.

685 x 881 x 881 x 645 = 342927333825

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.

685 : 1, 5, 137, 685

881 : 1, 881

881 : 1, 881

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,881,881,645, is 1.

Now, the common factors can be found like this.

685:5x 137

881:881

881:881

645:3x 5x 43

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

5x 881 = 4405

Therefore, the value for common factors is 4405.

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 = 342927333825/(1x4405)

LCM = 342927333825/4405

LCM = 77849565

Thus, we can understand that the LCM of 685,881,881,645 is 77849565.
