Calculate the LCM of 855,923,736,940

Given numbers are 855,923,736,940

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

The LCM of 855,923,736,940 is 27298795680.

Find LCM of 855,923,736,940 with Prime Factorization


2 855, 923, 736, 940
2 855, 923, 368, 470
5 855, 923, 184, 235
171, 923, 184, 47

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

2 x 2 x 5 x 171 x 923 x 184 x 47 = 27298795680

Therefore, the lowest common multiple of 855,923,736,940 is 27298795680.

LCM Formula to Find Lowest Common Multiple of 855,923,736,940

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.

855 x 923 x 736 x 940 = 545975913600

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

923 : 1, 13, 71, 923

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,923,736,940, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

923:13x 71

736:2x 2x 2x 2x 2x 23

940:2x 2x 5x 47

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 5 = 20

Therefore, the value for common factors is 20.

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 = 545975913600/(1x20)

LCM = 545975913600/20

LCM = 27298795680

Thus, we can understand that the LCM of 855,923,736,940 is 27298795680.
