Calculate the LCM of 760,342,819

Given numbers are 760,342,819

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

The LCM of 760,342,819 is 622440.

Find LCM of 760,342,819 with Prime Factorization


2 760, 342, 819
3 380, 171, 819
3 380, 57, 273
19 380, 19, 91
20, 1, 91

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

2 x 3 x 3 x 19 x 20 x 1 x 91 = 622440

Therefore, the lowest common multiple of 760,342,819 is 622440.

LCM Formula to Find Lowest Common Multiple of 760,342,819

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.

760 x 342 x 819 = 212874480

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.

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,342,819, is 1.

Now, the common factors can be found like this.

760:2x 2x 2x 5x 19

342:2x 3x 3x 19

819:3x 3x 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 3x 3x 19 = 342

Therefore, the value for common factors is 342.

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 = 212874480/(1x342)

LCM = 212874480/342

LCM = 622440

Thus, we can understand that the LCM of 760,342,819 is 622440.
