Calculate the LCM of 618,330,845,728

Given numbers are 618,330,845,728

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

The LCM of 618,330,845,728 is 160840680.

Find LCM of 618,330,845,728 with Prime Factorization


2 618, 330, 845, 728
3 309, 165, 845, 364
5 103, 55, 845, 364
13 103, 11, 169, 364
103, 11, 13, 28

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

2 x 3 x 5 x 13 x 103 x 11 x 13 x 28 = 160840680

Therefore, the lowest common multiple of 618,330,845,728 is 160840680.

LCM Formula to Find Lowest Common Multiple of 618,330,845,728

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.

618 x 330 x 845 x 728 = 125455730400

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

845 : 1, 5, 13, 65, 169, 845

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,330,845,728, is 1.

Now, the common factors can be found like this.

618:2x 3x 103

330:2x 3x 5x 11

845:5x 13x 13

728:2x 2x 2x 7x 13

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

2x 2x 3x 5x 13 = 780

Therefore, the value for common factors is 780.

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 = 125455730400/(1x780)

LCM = 125455730400/780

LCM = 160840680

Thus, we can understand that the LCM of 618,330,845,728 is 160840680.
