Calculate the LCM of 685,707,546,511,663

Given numbers are 685,707,546,511,663

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

The LCM of 685,707,546,511,663 is 46878787410.

Find LCM of 685,707,546,511,663 with Prime Factorization


3 685, 707, 546, 511, 663
7 685, 707, 182, 511, 221
13 685, 101, 26, 73, 221
685, 101, 2, 73, 17

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

3 x 7 x 13 x 685 x 101 x 2 x 73 x 17 = 46878787410

Therefore, the lowest common multiple of 685,707,546,511,663 is 46878787410.

LCM Formula to Find Lowest Common Multiple of 685,707,546,511,663

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 707 x 546 x 511 x 663 = 89585362740510

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

707 : 1, 7, 101, 707

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

511 : 1, 7, 73, 511

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,707,546,511,663, is 1.

Now, the common factors can be found like this.

685:5x 137

707:7x 101

546:2x 3x 7x 13

511:7x 73

663:3x 13x 17

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

3x 7x 7x 13 = 1911

Therefore, the value for common factors is 1911.

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 = 89585362740510/(1x1911)

LCM = 89585362740510/1911

LCM = 46878787410

Thus, we can understand that the LCM of 685,707,546,511,663 is 46878787410.
