Calculate the LCM of 312,760,120,778

Given numbers are 312,760,120,778

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

The LCM of 312,760,120,778 is 11529960.

Find LCM of 312,760,120,778 with Prime Factorization


2 312, 760, 120, 778
2 156, 380, 60, 389
2 78, 190, 30, 389
3 39, 95, 15, 389
5 13, 95, 5, 389
13, 19, 1, 389

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

2 x 2 x 2 x 3 x 5 x 13 x 19 x 1 x 389 = 11529960

Therefore, the lowest common multiple of 312,760,120,778 is 11529960.

LCM Formula to Find Lowest Common Multiple of 312,760,120,778

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.

312 x 760 x 120 x 778 = 22137523200

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.

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

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

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

778 : 1, 2, 389, 778

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,760,120,778, is 2.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

760:2x 2x 2x 5x 19

120:2x 2x 2x 3x 5

778:2x 389

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 2x 2x 2x 2x 3x 5 = 960

Therefore, the value for common factors is 960.

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 = 22137523200/(2x960)

LCM = 22137523200/1920

LCM = 11529960

Thus, we can understand that the LCM of 312,760,120,778 is 11529960.
