Calculate the LCM of 306,849,691,663

Given numbers are 306,849,691,663

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

The LCM of 306,849,691,663 is 777909834.

Find LCM of 306,849,691,663 with Prime Factorization


3 306, 849, 691, 663
17 102, 283, 691, 221
6, 283, 691, 13

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

3 x 17 x 6 x 283 x 691 x 13 = 777909834

Therefore, the lowest common multiple of 306,849,691,663 is 777909834.

LCM Formula to Find Lowest Common Multiple of 306,849,691,663

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.

306 x 849 x 691 x 663 = 119020204602

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.

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

849 : 1, 3, 283, 849

691 : 1, 691

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 306,849,691,663, is 1.

Now, the common factors can be found like this.

306:2x 3x 3x 17

849:3x 283

691:691

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 3x 17 = 153

Therefore, the value for common factors is 153.

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 = 119020204602/(1x153)

LCM = 119020204602/153

LCM = 777909834

Thus, we can understand that the LCM of 306,849,691,663 is 777909834.
